Pay less money for energy—
and more attention to the environment.
It’s pretty obvious, really. An efficient steam trap wastes less
energy, which means you burn less fuel and reduce emissions.
The results are energy savings and a cleaner, healthier environment.
By helping companies manage energy, Armstrong steam traps
are also helping protect the world we all share.
As a steam trap wears, it loses efficiency and begins to waste energy.
But Armstrong inverted bucket traps last years longer than other
traps. They operate more efficiently longer because the inverted
bucket is the most reliable steam trap operating principle known.
Clearly, the longer an efficient trap lasts, the more it reduces energy
wasted, fuel burned and pollutants released into the air. It’s an
all-around positive situation that lets the environment win, too.
Bringing energy down to earth in your facility could begin with a
renewed focus on your steam system, especially your steam traps.
Said another way: Zeroing in your steam traps is an easy way to
pay less money for energy—and more attention to the environment.
Companies around the world are beginning to realize that rather
than being separate challenges, energy and the environment are
and have always been a single mission. And that quality management
in one area will surely impact the other.

The Inverted Bucket Steam Trap
Resistance to damage from water hammer
Open bucket or float will not collapse as a result of water hammer.
Wear and corrosion resistance
Free-floating guided lever valve mechanism
is “frictionless,” and all wear points
are heavily reinforced. All working
parts are stainless steel. Valve and
seat are stainless steel, individually
ground and lapped together
in matched sets.
Continuous air
and CO2 venting
Vent in top of bucket provides
continuous automatic air and CO2
venting with no cooling lag or threat
of air binding. Steam passing
through vent is less than that
required to compensate for
radiation losses from the trap
so it’s not wasted.
Excellent operation
against back pressure
Since trap operation is governed by
the difference in density of steam
and water, back pressure in the
return line has no effect on the ability
of the trap to open for condensate
and close against steam.
Virtually no steam loss
Steam does not reach the
water-sealed discharge valve.
Purging action
Snap opening of the valve
creates a momentary
pressure drop and turbulence
in the unit drained. This breaks
up films of condensate and air
and speeds their flow to
the trap.
Dependable operation
Simple, direct operation with
nothing to stick, bind or clog.
Only two moving parts—
the valve lever and the bucket.
Freedom from dirt problems
Condensate flow under the bottom edge of
the bucket keeps sediment and sludge in
suspension until it is discharged with the
condensate. Valve orifice opens wide and
closes tightly. No buildup of dirt or close
clearances to be affected by scale.
The inverted bucket is the most reliable steam trap operating principle
known. The heart of its simple design is a unique leverage system
that multiplies the force provided by the bucket to open the valve
against pressure. Since the bucket is open at the bottom, it resists
damage from water hammer, and wear points are heavily reinforced for
long life.
The inverted bucket has only two moving parts—the valve lever
assembly and the bucket. That means no fixed points, no complicated
linkages. Nothing to stick, bind or clog.

Conserves Energy Even in the Presence of Wear
Armstrong inverted bucket steam traps open and close based on
the difference in density between condensate and steam—the
inverted bucket principle. They open and close gently, minimizing
wear. This simple fact means that inverted buckets are subject to
less wear than some other types of traps.
In fact, as an Armstrong inverted bucket trap wears, its tight seal
actually improves. The ball valve and seat of the Armstrong trap
provide essentially line contact—resulting in a tight seal because
the entire closing force is concentrated on one narrow seating ring.
An Armstrong inverted bucket trap continues to operate efficiently
with use. Gradual wear slightly increases the diameter of the seat
and alters the shape and diameter of the ball valve. But, as this occurs,
a tight seal is still preserved—the ball merely seats itself deeper.
Corrosion-Resistant Parts
The stainless steel valve and seat of the Armstrong inverted bucket
steam trap are individually ground and lapped together in matched
sets. All other working parts are wear- and corrosion-resistant
stainless steel.
Venting of Air and CO2
The Armstrong inverted bucket provides continuous automatic air
and CO2
venting with no cooling lag or threat of air binding.
Operation Against Back Pressure
The Armstrong inverted bucket has excellent performance
against back pressure. It has no adverse effect on inverted bucket
operation other than to reduce its capacity by the low differential.
The bucket simply requires less force to pull the valve open and
cycle the trap.
Freedom From Dirt Problems
Armstrong designed its inverted bucket to be virtually free of dirt
problems. The valve and seat are at the top of the trap, far away
from the larger particles of dirt, which fall to the bottom. Here the
up-and-down action of the bucket pulverizes them. Since the valve
of an inverted bucket is either fully closed or open, dirt particles
pass freely. And the swift flow of condensate from under the
bucket’s edge creates a unique self-scrubbing action that
sweeps dirt out of the trap.

How to Use the IB Trap Summary Capacity Chart
ST-9
This catalog should be utilized as a guide for the installation and
operation of steam trapping equipment by experienced personnel.
Selection or installation should always be accompanied by competent
technical assistance or advice. Armstrong and its local representatives
are available for consultation and technical assistance. We encourage
you to contact your Armstrong Representative for complete details.
The summary capacity chart plots actual trap capacity vs. inlet
pressure on a log-log grid. The trap capacities become straight lines
on this grid. The small numbers along the pressure axis identify
the subdivisions; for example, between the large 10 and 100, the
numbers 2, 3, 5, and 7 represent 20, 30, 50 and 70 psi.
The summary chart combines many trap families into one chart by
presenting only a portion of the capacity line for each orifice size.
For charts that give capacity over a wide range of pressures, see
the specific trap model pages.
Individual capacity charts for various traps are given throughout
this catalog. Those charts show capacity lines for each orifice, with
pressures usually from 1 psi up to the maximum rated pressure of
that orifice.
To select an inverted bucket steam trap using the summary capacity
chart, you must know the condensate load, safety factor, inlet pressure
and outlet pressure. Remember, the object is to select a trap that
can 1) operate at the maximum inlet pressure, and 2) handle the
capacity at the minimum differential pressure. Consider the following
typical problems.
Example 1. Constant pressure, condensing rate.
Given:
Maximum inlet pressure . . . . . . . . . . . . . . . . . . . . . . . . .70 psi
Normal operating differential pressure . . . . . . . . . . . . . . .60 psi
Required capacity = 300 lb/hr condensate load
times 3:1 safety factor, or . . . . . . . . . . . . . . . . . . . . . .900 lb/hr
Enter the chart at the 60 psi line and go up to 900 lb/hr capacity.
This is directly on the 5/32'' orifice line for models 211, 811 and 881
(and other traps). Now follow this line to the right, to the vertical
drop at 70 psi. This means the orifice will work, in these traps, up
to a maximum differential of 70 psi. Assuming a cast iron trap is
suitable, the 5/32'' orifice in a Model 211, 811 or 881 trap will meet
all the operating requirements.
Example 2. Constant condensing rate but with possible reduced
inlet pressure.
Given:
Maximum inlet pressure . . . . . . . . . . . . . . . . . . . . . . . .100 psi
Minimum inlet pressure . . . . . . . . . . . . . . . . . . . . . . . . .40 psi
Required capacity = 400 lb/hr condensate load
times 3:1 safety factor, or . . . . . . . . . . . . . . . . . . . .1,200 lb/hr
Consider the maximum operating pressure first. Enter the chart at
the 100 psi line and find the first capacity line above 1,200 lb/hr.
This is the 5/32'' orifice in a Model 212, 812 or 882, and it has
a capacity of 1,800 lb/hr at 100 psi. Now extend this straight line
to the left until it intersects the 40 psi pressure line. At 40 psi, read
a capacity of 1,300 lb/hr. (You could also refer to the individual
capacity charts for Models 212, 812 or 882.) Assuming cast iron is
suitable, this is the desired trap selection to meet the requirements
of opening at the maximum pressure, and also having the needed
capacity at the minimum pressure.
This example points out how the capacity is influenced by the trap
size. Example 1 also used the same orifice size, but in a physically
smaller trap. In the larger trap the same diameter orifice not only
has a higher capacity, it will work at higher pressures.
Example 3. Constant condensing rate but high back pressure.
Given:
Inlet pressure . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .100 psi
Normal outlet (back) pressure . . . . . . . . . . . . . . . . . . . . .50 psi
Required capacity = 1,800 lb/hr condensate load
times 3:1 safety factor, or . . . . . . . . . . . . . . . . . . . .5,400 lb/hr
Traditional method:
Since the differential pressure is only 50 psi, enter the chart at 50 psi
and go up to a capacity of 5,400 lb/hr. This is just under the capacity
lines for Models 214 and 814. However, the 5/16'' orifice is the largest
orifice that will operate at 100 psi inlet pressure. (Remember that
the back pressure may not always be there!) Extend the capacity
line for the 5/16'' orifice to the left, and read a capacity of 4,800 lb/hr
at 50 psi. Since this is too low, go up to the 215/815 capacity lines
and repeat the process. The selection will end up being a Model 215
or 815 with a 3/8'' orifice*.
About this chart ...
The Armstrong capacity chart shows continuous discharge capacities
of Armstrong traps under actual operating conditions, as determined
by many hundreds of tests made over the years. In these tests,
hot condensate was used, at or near the steam temperature
corresponding to the test pressure. The choking effect of flash steam
in the orifice and the back pressure created by this flash steam were
therefore automatically taken into account. The test setups were similar
to an actual installation hookup, so that pipe friction in both inlet and
discharge lines was reflected in the results.
* This method is conservative. While it will always select a workable
trap, it may select a larger trap than necessary. Consult Armstrong
Application Engineering for further information about the effects
of back pressure.

200 Series Inverted Bucket Steam Traps
Cast Iron for Vertical Installation
For Pressures to 250 psig (17 bar)...Capacities to 20,000 lb/hr (9,072 kg/hr)
Description
The most reliable steam trap known—the inverted bucket—provides efficient
condensate drainage of virtually all types of steam-using equipment. Put the
inverted bucket to work in a tough cast iron package, and you have the best
of both worlds. Because they operate efficiently for longer periods of time,
Armstrong cast iron inverted buckets add solid energy savings to lower
replacement/labor costs.
A unique leverage system multiplies the force provided by the bucket to open
the valve against system pressure. The mechanism is free-floating, and has
no fixed pivots to create wear or friction.
Because the mechanism is located at the top of the trap, no dirt can collect
on the orifice. Small particles of dirt are held in suspension until discharged
by the full differential purging action when the bucket sinks, pulling the valve
off the seat.
The discharge orifice is surrounded by a water seal, preventing live steam
loss. Automatic air venting is provided by a small vent hole in the bucket, which
provides continuous automatic air and CO2 venting at steam temperature.
Inverted bucket traps drain continuously, although discharging intermittently,
allowing no condensate backup. They are also resistant to water hammer.

Description
Armstrong offers two sizes of cast steel traps with in-line horizontal pipe
connections and integral strainers with a choice of screwed, socketweld
or flanged connections.
A unique leverage system multiplies the force provided by the bucket to open
the valve against system pressure. The mechanism is free-floating, and has
no fixed pivots to create wear or friction.
Because the mechanism is located at the top of the trap, no dirt can collect
on the orifice. Small particles of dirt are held in suspension until discharged
by the full differential purging action when the bucket sinks, pulling the valve
off the seat.
The discharge orifice is surrounded by a water seal, preventing live steam

provides continuous automatic air and CO2 venting at steam temperature.

Description
Armstrong offers its 300 Series forged carbon steel traps for vertical installation
with a choice of screwed, socketweld or flanged connections.
A unique leverage system multiplies the force provided by the bucket to open
the valve against system pressure. The mechanism is free-floating, and has
no fixed pivots to create wear or friction.
Because the mechanism is located at the top of the trap, no dirt can collect
on the orifice. Small particles of dirt are held in suspension until discharged
by the full differential purging action when the bucket sinks, pulling the valve
off the seat.
The discharge orifice is surrounded by a water seal, preventing live steam
loss. Automatic air venting is provided by a small vent hole in the bucket, which
provides continuous automatic air and CO2 venting at steam temperature.
Inverted bucket traps drain continuously, allowing no condensate backup.
They are also resistant to water hammer.
For Superheat Service:
1. Don’t oversize the orifice; a restricted orifice may be advisable.
2. Specify a burnished valve and seat and an extended inlet tube
and check valve.
3. Provide a drip leg of adequate diameter and length.
4. Provide a generous length (2'-3') of inlet piping, with the trap
below the main.
5. Don’t insulate the trap or the inlet piping.

Description
Armstrong Model 411G vertical installation and Model 421 horizontal installation
offer smaller capacities at higher pressures.
A unique leverage system multiplies the force provided by the bucket to open
the valve against system pressure. The mechanism is free-floating and has
no fixed pivots to create wear or friction.
Because the mechanism is located at the top of the trap, no dirt can collect
on the orifice. Small particles of dirt are held in suspension until discharged
by the full differential purging action when the bucket sinks, pulling the valve
off the seat.
The discharge orifice is surrounded by a water seal, preventing live steam
loss. Automatic air venting is provided by a small vent hole in the bucket.
Inverted bucket traps drain continuously to prevent condensate backup.
They are also resistant to water hammer.
Model 421 adds the convenience and savings of in-line repairability and is
designed to meet today’s energy-management requirements efficiently and
economically over a long, trouble-free service life.

Armstrong offers its 400 Series forged chrome-moly steel traps for vertical

This provides continuous automatic air and CO2 venting at steam temperature.
Inverted bucket traps drain continuously to prevent condensate backup.
They are also resistant to water hammer.
Operation on Superheat. A normally operating bucket trap is filled with
saturated steam and condensate. Superheated steam can enter only as fast
as the steam inside can condense. As a result, the temperature of the trap is
at (or slightly below) saturated steam temperature, regardless of the degree
of superheat.
Trap Selection. The pressure-containing parts of the steam trap should safely
withstand the maximum pressure and temperature conditions of the system.
For example, a trap is required for a 900 psig (62 bar) main at 900°F (482°C).
The normal operating temperature of the trap will be about 532°F (278°C).
A Model 415 trap should be selected, even though several smaller traps are
capable of handling the working pressure.
For Superheat Service:
1. Don’t oversize the orifice; a restricted orifice may be advisable.
2. Specify a burnished valve and seat and an extended inlet tube
and check valve.
3. Provide a drip leg of adequate diameter and length.
4. Provide a generous length (2'-3') of inlet piping, with the trap
below the main.
5. Don’t insulate the trap or the inlet piping.

Description
Armstrong’s 401-SH/501-SH Series inverted bucket steam trap line is
made for overcoming the difficult combination of superheat and high
pressure/low load service.
To survive this most severe steam service, Armstrong created an inverted
bucket trap with a unique accumulation chamber. The chamber collects
sufficient condensate to ensure full discharge cycles. A cup in the chamber
floats up and down on the steam inlet tube, sealing it off as the condensate
level rises. At the same time as the chamber collects condensate, steam
continues to flow under the bucket, making sure that the discharge valve
closes tightly until the condensate rises into the trap body and the bucket
falls down. The operation is on/off, no throttling or dribbling.
Furthermore, it combines all the advantages of an inverted bucket steam trap:
• High resistance to wear, corrosion and water hammer with no gaskets.
• A unique leverage system multiplies the force provided by the bucket,
to open the valve against system pressure.
• The mechanism is located at the top. No dirt can collect on the orifice.
Small particles of dirt will be held in suspension until discharged by the full
differential purging action.
• The discharge orifice is surrounded by a water seal, preventing live steam
loss. Automatic air venting is provided by a small hole in the bucket.
• Inverted bucket traps require no adjustment. They do not allow condensate
backup and are resistant to water hammer.

Installation Recommendations
What little condensate there is on superheat and high pressure/low load
service usually forms in drip legs and in the traps themselves. Therefore
proper piping and drip legs of adequate size and diameter are essential
for the successful operation of the Armstrong superheat trap.
Drip Leg Sizing
The properly sized drip leg will capture condensate. Too small a drip leg can actually
cause a venturi “piccolo” effect where pressure drop pulls condensate out of the drip
leg and trap.
D
H
M
Trap Draining Drip Leg on Steam Main
Cycling—Discharge Valve Wide Open
With the steam feed tube to the trap chamber
sealed, condensate flows through the
condensate feed tube (from accumulation
chamber) into the trap chamber. This
sinks the inverted bucket, which opens
the discharge valve, cycling the trap.
Cycle Ending
As the level of condensate in the accu-
mulation chamber falls, the cup sealing
the steam feed tube moves downward,
opening a passage for steam to flow
into trap chamber.
Trap Closed
As steam begins to flow through
the accumulation chamber and up
the steam feed tube under the inverted
bucket in the trap chamber, the
discharge valve closes tightly.
Cycle About to Repeat
As the level of condensate rises in the
accumulation chamber, the cup floats
up until it again seals the steam feed
tube, and the cycle repeats.

Description
Armstrong offers its 5000 Series forged chrome-moly steel traps for vertical
installation with a choice of screwed, socketweld or flanged connections.
A unique leverage system multiplies the force provided by the bucket to open
the valve against system pressure. The mechanism is free-floating and has
no fixed pivots to create wear or friction.
Because the mechanism is located at the top of the trap, no dirt can collect
on the orifice. Small particles of dirt are held in suspension until discharged
by the full differential purging action when the bucket sinks, pulling the valve
off the seat.
The discharge orifice is surrounded by a water seal, preventing live steam loss.
Automatic air venting is provided by a small vent hole in the bucket.This provides
continuous automatic air and CO2 venting at steam temperature.
Inverted bucket traps drain continuously, although discharging intermittently,
to prevent condensate backup. They are also resistant to water hammer.
Operation on Superheat. A normally operating bucket trap is filled with
saturated steam and condensate. Superheated steam can enter only as fast
as the steam inside can condense. As a result, the temperature of the trap
is at (or slightly below) saturated steam temperature, regardless of the degree
of superheat.
Trap Selection. The pressure-containing parts of the steam trap should safely
withstand the maximum pressure and temperature conditions of the system.
For example, a trap is required for a 1,000 psig (68 bar) main at 950°F
(510°C). The normal operating temperature of the trap will be about 546°F
(286°C). A Model 5133G trap should be selected, even though several smaller
traps are capable of handling the working pressure.
For Superheat Service:
1. Don’t oversize the orifice; a restricted orifice may be advisable.
2. Specify a burnished valve and seat and an extended inlet tube and
check valve.
3. Provide a drip leg of adequate diameter and length.
4. Provide a generous length (2'-3') of inlet piping, with the trap below the main.
5. Don’t insulate the trap or the inlet piping.

2000 Series Stainless Steel Traps
Wear and corrosion resistance
Free-floating guided lever valve mechanism is
“frictionless,” and all wear points are heavily
reinforced. All working parts are stainless steel.
Valve and seat are stainless steel, individually
ground and lapped together in matched sets.
Continuous air and CO2 venting
Vent in top of bucket provides continuous automatic
air and CO2 venting with no cooling lag or threat of
air binding. Steam passing through vent is less than
that required to compensate for radiation losses
from the trap, so it’s not wasted.
Purging action
Snap opening of the valve creates
a momentary pressure drop and
turbulence in the unit drained.
This breaks up films of condensate
and air and speeds their flow to
the trap.
Virtually no steam loss
Steam does not reach the
water-sealed discharge valve.
Dependable operation
Simple, direct operation with
nothing to stick, bind or clog.
Only two moving parts—
the valve lever and the bucket.
Excellent operation
against back pressure
Since trap operation is governed by
the difference in density of steam and
water, back pressure in the return line
has no effect on the ability of the trap
to open for condensate and close
against steam.
Freedom from dirt problems
Condensate flow under the bottom edge of
the bucket keeps sediment and sludge in
suspension until it is discharged with the
condensate. Valve orifice opens wide and
closes tightly. No buildup of dirt or
close clearances to be affected by scale.Resistance to damage from water hammer
Open bucket or float will not collapse as a
result of water hammer.
360° universal 304 stainless steel connector
Provides quick, easy in-line renewability along with all the proven advantages
of an inverted bucket operation. Also available with optional IS-2
integral strainer connector with 20 x 20 mesh stainless steel strainer.
Sealed, tamperproof 304-L
stainless steel package
Able to withstand freeze-ups
without damage.
The Armstrong stainless steel traps—Series 1000, Series U-1000,
Series 1800 and Series 2000—have high resistance to damage from
freeze-ups. They also offer high resistance to wear and corrosion for
longer service reliability, and they provide continuous air venting.
Armstrong stainless steel traps provide maximum ease and economy
of installation, inspection or replacement. What’s more, an Armstrong
stainless steel trap is the ideal solution for trapping applications such
as tracer lines, steam mains, and heating and processing applications.

Description
Armstrong 1000 Series stainless steel inverted bucket steam traps normally
last three to four times longer than conventional traps used in identical services.
Heat-treated stainless steel valves and seats are of the same design, material
and workmanship as those used in traps for pressures up to 900 psig and
temperatures to 900°F. More compact than cast iron or carbon steel equivalents,
1000 Series traps are ideal for trapping applications such as tracer lines,
steam mains and heating/process applications.
For simple installation, inspection and replacement, Armstrong offers
U-1000 Series all-stainless steel inverted bucket traps with union
connections. U-1000 Series are also offered with integral carbon steel
strainers with .045'' perforated stainless steel screens.
Both the 1000 and U-1000 Series are guaranteed for three years.

Pop Drain for Freeze Protection
In general, a properly selected and
installed Armstrong trap will not freeze
as long as steam is coming to the trap.
If the steam supply is shut off, a pop
drain should be used to automatically
drain the trap. Stainless steel pop drain
available for Models 1811 and 1822.
Maximum Operating Conditions
Pressure: 600 psig (41 bar)
Temperature: 350°F (177°C)
Insu-Pak™
Now you can insulate the in-line traps
in your plant without complicating regular
trap maintenance. Insu-Pak, a simple
reusable insulation package, cuts the time
and cost of in-field installation because it
goes on in a snap. And it comes off just as
easily. Insu-Pak can prevent trap freeze-
up when used with a properly designed
condensate manifold. Designed for use
with Model 1810 and Model 1811 traps.
Probe connections are available for
trap monitoring on Models 1811 and 1822.

*NOTE: Because the orifice is located at the top, inverted bucket steam traps
handle dirt and scale better than other types of traps. However, in applications
where extremely dirty conditions exist, care should be exercised in the use of
all types of restricted-orifice, reduced-capacity traps.

trap. If the steam supply is shut off,
a pop drain should be used to auto-
matically drain the trap. Stainless steel
pop drain available for Models 2011
and 2022.
Maximum Operating Conditions
Pressure: 600 psig (41 bar)

Insu-Pak™
Now you can insulate the in-line traps in
your plant without complicating regular
trap maintenance. Insu-Pak, a simple
reusable insulation package, cuts the
time and cost of in-field installation
because it goes on in a snap. And it
comes off just as easily. The Insu-Pak
can prevent trap freeze-up when used
with a properly designed condensate
manifold. Designed for use with Model
2010 and Model 2011 traps.
Probe connections are available
for trap monitoring for Models 2011
and 2022.

Connectors
Besides the inverted bucket
traps, the standard connector
or IS-2 connector with integral
strainer can also be used on
thermostatic, thermostatic
wafer and disc traps.

*NOTE: Because the orifice is located at the top, inverted bucket steam traps
handle dirt and scale better than other types of traps. However, in applications
where extremely dirty conditions exist, care should be exercised in the use of
all types of restricted-orifice, reduced-capacity traps.

An efficient steam trap wastes less energy, which means you burn less fuel and reduce emissions. The results are energy savings and a cleaner, healthier environment. By helping companies manage energy, Armstrong steam traps are also helping protect the world we all share. As a steam trap wears, it loses efficiency and begins to waste energy. But Armstrong inverted bucket traps last years longer than other traps. They operate more efficiently longer because the inverted bucket is the most reliable steam trap operating principle known. Clearly, the longer an efficient trap lasts, the more it reduces energy wasted, fuel burned and pollutants released into the air. It’s an all-around positive situation that lets the environment win, too. Bringing energy down to earth in your facility could begin with a renewed focus on your steam system, especially your steam traps. Said another way: Zeroing in your steam traps is an easy way to pay less money for energy—and more attention to the environment. Companies around the world are beginning to realize that rather than being separate challenges, energy and the environment are and have always been a single mission. And that quality management in one area will surely impact the other.

Wear and corrosion resistance Free-floating guided lever valve mechanism is “frictionless,” and all wear points are heavily reinforced. All working parts are stainless steel. Valve and seat are stainless steel, individually ground and lapped together in matched sets. Continuous air and CO2 venting Vent in top of bucket provides continuous automatic air and CO2 venting with no cooling lag or threat of air binding. Steam passing through vent is less than that required to compensate for radiation losses from the trap so it’s not wasted. Excellent operation against back pressure Since trap operation is governed by the difference in density of steam and water, back pressure in the return line has no effect on the ability of the trap to open for condensate and close against steam. Virtually no steam loss Steam does not reach the water-sealed discharge valve. Purging action Snap opening of the valve creates a momentary pressure drop and turbulence in the unit drained. This breaks up films of condensate and air and speeds their flow to the trap. Dependable operation Simple, direct operation with nothing to stick, bind or clog. Only two moving parts— the valve lever and the bucket. Freedom from dirt problems Condensate flow under the bottom edge of the bucket keeps sediment and sludge in suspension until it is discharged with the condensate. Valve orifice opens wide and closes tightly. No buildup of dirt or close clearances to be affected by scale. The inverted bucket is the most reliable steam trap operating principle known. The heart of its simple design is a unique leverage system that multiplies the force provided by the bucket to open the valve against pressure. Since the bucket is open at the bottom, it resists damage from water hammer, and wear points are heavily reinforced for long life. The inverted bucket has only two moving parts—the valve lever assembly and the bucket. That means no fixed points, no complicated linkages. Nothing to stick, bind or clog.

They open and close gently, minimizing wear. This simple fact means that inverted buckets are subject to less wear than some other types of traps. In fact, as an Armstrong inverted bucket trap wears, its tight seal actually improves. The ball valve and seat of the Armstrong trap provide essentially line contact—resulting in a tight seal because the entire closing force is concentrated on one narrow seating ring. An Armstrong inverted bucket trap continues to operate efficiently with use. Gradual wear slightly increases the diameter of the seat and alters the shape and diameter of the ball valve. But, as this occurs, a tight seal is still preserved—the ball merely seats itself deeper. Corrosion-Resistant Parts The stainless steel valve and seat of the Armstrong inverted bucket steam trap are individually ground and lapped together in matched sets. All other working parts are wear- and corrosion-resistant stainless steel. Venting of Air and CO2 The Armstrong inverted bucket provides continuous automatic air and CO2 venting with no cooling lag or threat of air binding. Operation Against Back Pressure The Armstrong inverted bucket has excellent performance against back pressure. It has no adverse effect on inverted bucket operation other than to reduce its capacity by the low differential. The bucket simply requires less force to pull the valve open and cycle the trap. Freedom From Dirt Problems Armstrong designed its inverted bucket to be virtually free of dirt problems. The valve and seat are at the top of the trap, far away from the larger particles of dirt, which fall to the bottom. Here the up-and-down action of the bucket pulverizes them. Since the valve of an inverted bucket is either fully closed or open, dirt particles pass freely. And the swift flow of condensate from under the bucket’s edge creates a unique self-scrubbing action that sweeps dirt out of the trap.

Box 408, Three Rivers, MI 49093 – USA Phone: (269) 273-1415 Fax: (269) 278-6555 www.armstrong-intl.com How to Use the IB Trap Summary Capacity Chart ST-9 This catalog should be utilized as a guide for the installation and operation of steam trapping equipment by experienced personnel. Selection or installation should always be accompanied by competent technical assistance or advice. Armstrong and its local representatives are available for consultation and technical assistance. We encourage you to contact your Armstrong Representative for complete details. The summary capacity chart plots actual trap capacity vs. inlet pressure on a log-log grid. The trap capacities become straight lines on this grid. The small numbers along the pressure axis identify the subdivisions; for example, between the large 10 and 100, the numbers 2, 3, 5, and 7 represent 20, 30, 50 and 70 psi. The summary chart combines many trap families into one chart by presenting only a portion of the capacity line for each orifice size. For charts that give capacity over a wide range of pressures, see the specific trap model pages. Individual capacity charts for various traps are given throughout this catalog. Those charts show capacity lines for each orifice, with pressures usually from 1 psi up to the maximum rated pressure of that orifice. To select an inverted bucket steam trap using the summary capacity chart, you must know the condensate load, safety factor, inlet pressure and outlet pressure. Remember, the object is to select a trap that can 1) operate at the maximum inlet pressure, and 2) handle the capacity at the minimum differential pressure. Consider the following typical problems. Example 1. Constant pressure, condensing rate. Given: Maximum inlet pressure . . . . . . . . . . . . . . . . . . . . . . . . .70 psi Normal operating differential pressure . . . . . . . . . . . . . . .60 psi Required capacity = 300 lb/hr condensate load times 3:1 safety factor, or . . . . . . . . . . . . . . . . . . . . . .900 lb/hr Enter the chart at the 60 psi line and go up to 900 lb/hr capacity. This is directly on the 5/32'' orifice line for models 211, 811 and 881 (and other traps). Now follow this line to the right, to the vertical drop at 70 psi. This means the orifice will work, in these traps, up to a maximum differential of 70 psi. Assuming a cast iron trap is suitable, the 5/32'' orifice in a Model 211, 811 or 881 trap will meet all the operating requirements. Example 2. Constant condensing rate but with possible reduced inlet pressure. Given: Maximum inlet pressure . . . . . . . . . . . . . . . . . . . . . . . .100 psi Minimum inlet pressure . . . . . . . . . . . . . . . . . . . . . . . . .40 psi Required capacity = 400 lb/hr condensate load times 3:1 safety factor, or . . . . . . . . . . . . . . . . . . . .1,200 lb/hr Consider the maximum operating pressure first. Enter the chart at the 100 psi line and find the first capacity line above 1,200 lb/hr. This is the 5/32'' orifice in a Model 212, 812 or 882, and it has a capacity of 1,800 lb/hr at 100 psi. Now extend this straight line to the left until it intersects the 40 psi pressure line. At 40 psi, read a capacity of 1,300 lb/hr. (You could also refer to the individual capacity charts for Models 212, 812 or 882.) Assuming cast iron is suitable, this is the desired trap selection to meet the requirements of opening at the maximum pressure, and also having the needed capacity at the minimum pressure. This example points out how the capacity is influenced by the trap size. Example 1 also used the same orifice size, but in a physically smaller trap. In the larger trap the same diameter orifice not only has a higher capacity, it will work at higher pressures. Example 3. Constant condensing rate but high back pressure. Given: Inlet pressure . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .100 psi Normal outlet (back) pressure . . . . . . . . . . . . . . . . . . . . .50 psi Required capacity = 1,800 lb/hr condensate load times 3:1 safety factor, or . . . . . . . . . . . . . . . . . . . .5,400 lb/hr Traditional method: Since the differential pressure is only 50 psi, enter the chart at 50 psi and go up to a capacity of 5,400 lb/hr. This is just under the capacity lines for Models 214 and 814. However, the 5/16'' orifice is the largest orifice that will operate at 100 psi inlet pressure. (Remember that the back pressure may not always be there!) Extend the capacity line for the 5/16'' orifice to the left, and read a capacity of 4,800 lb/hr at 50 psi. Since this is too low, go up to the 215/815 capacity lines and repeat the process. The selection will end up being a Model 215 or 815 with a 3/8'' orifice*. About this chart ... The Armstrong capacity chart shows continuous discharge capacities of Armstrong traps under actual operating conditions, as determined by many hundreds of tests made over the years. In these tests, hot condensate was used, at or near the steam temperature corresponding to the test pressure. The choking effect of flash steam in the orifice and the back pressure created by this flash steam were therefore automatically taken into account. The test setups were similar to an actual installation hookup, so that pipe friction in both inlet and discharge lines was reflected in the results. * This method is conservative. While it will always select a workable trap, it may select a larger trap than necessary. Consult Armstrong Application Engineering for further information about the effects of back pressure.

Put the inverted bucket to work in a tough cast iron package, and you have the best of both worlds. Because they operate efficiently for longer periods of time, Armstrong cast iron inverted buckets add solid energy savings to lower replacement/labor costs. A unique leverage system multiplies the force provided by the bucket to open the valve against system pressure. The mechanism is free-floating, and has no fixed pivots to create wear or friction. Because the mechanism is located at the top of the trap, no dirt can collect on the orifice. Small particles of dirt are held in suspension until discharged by the full differential purging action when the bucket sinks, pulling the valve off the seat. The discharge orifice is surrounded by a water seal, preventing live steam loss. Automatic air venting is provided by a small vent hole in the bucket, which provides continuous automatic air and CO2 venting at steam temperature. Inverted bucket traps drain continuously, although discharging intermittently, allowing no condensate backup. They are also resistant to water hammer.

A unique leverage system multiplies the force provided by the bucket to open the valve against system pressure. The mechanism is free-floating, and has no fixed pivots to create wear or friction. Because the mechanism is located at the top of the trap, no dirt can collect on the orifice. Small particles of dirt are held in suspension until discharged by the full differential purging action when the bucket sinks, pulling the valve off the seat. The discharge orifice is surrounded by a water seal, preventing live steam loss. Automatic air venting is provided by a small vent hole in the bucket, which provides continuous automatic air and CO2 venting at steam temperature. Inverted bucket traps drain continuously, allowing no condensate backup. They are also resistant to water hammer. For Superheat Service: 1. Don’t oversize the orifice; a restricted orifice may be advisable. 2. Specify a burnished valve and seat and an extended inlet tube and check valve. 3. Provide a drip leg of adequate diameter and length. 4. Provide a generous length (2'-3') of inlet piping, with the trap below the main. 5. Don’t insulate the trap or the inlet piping.

This provides continuous automatic air and CO2 venting at steam temperature. Inverted bucket traps drain continuously to prevent condensate backup. They are also resistant to water hammer. Operation on Superheat. A normally operating bucket trap is filled with saturated steam and condensate. Superheated steam can enter only as fast as the steam inside can condense. As a result, the temperature of the trap is at (or slightly below) saturated steam temperature, regardless of the degree of superheat. Trap Selection. The pressure-containing parts of the steam trap should safely withstand the maximum pressure and temperature conditions of the system. For example, a trap is required for a 900 psig (62 bar) main at 900°F (482°C). The normal operating temperature of the trap will be about 532°F (278°C). A Model 415 trap should be selected, even though several smaller traps are capable of handling the working pressure. For Superheat Service: 1. Don’t oversize the orifice; a restricted orifice may be advisable. 2. Specify a burnished valve and seat and an extended inlet tube and check valve. 3. Provide a drip leg of adequate diameter and length. 4. Provide a generous length (2'-3') of inlet piping, with the trap below the main. 5. Don’t insulate the trap or the inlet piping.

Box 408, Three Rivers, MI 49093 – USA Phone: (269) 273-1415 Fax: (269) 278-6555 www.armstrong-intl.com Description Armstrong’s 401-SH/501-SH Series inverted bucket steam trap line is made for overcoming the difficult combination of superheat and high pressure/low load service. To survive this most severe steam service, Armstrong created an inverted bucket trap with a unique accumulation chamber. The chamber collects sufficient condensate to ensure full discharge cycles. A cup in the chamber floats up and down on the steam inlet tube, sealing it off as the condensate level rises. At the same time as the chamber collects condensate, steam continues to flow under the bucket, making sure that the discharge valve closes tightly until the condensate rises into the trap body and the bucket falls down. The operation is on/off, no throttling or dribbling. Furthermore, it combines all the advantages of an inverted bucket steam trap: • High resistance to wear, corrosion and water hammer with no gaskets. • A unique leverage system multiplies the force provided by the bucket, to open the valve against system pressure. • The mechanism is located at the top. No dirt can collect on the orifice. Small particles of dirt will be held in suspension until discharged by the full differential purging action. • The discharge orifice is surrounded by a water seal, preventing live steam loss. Automatic air venting is provided by a small hole in the bucket. • Inverted bucket traps require no adjustment. They do not allow condensate backup and are resistant to water hammer.

Therefore proper piping and drip legs of adequate size and diameter are essential for the successful operation of the Armstrong superheat trap. Drip Leg Sizing The properly sized drip leg will capture condensate. Too small a drip leg can actually cause a venturi “piccolo” effect where pressure drop pulls condensate out of the drip leg and trap. D H M Trap Draining Drip Leg on Steam Main Cycling—Discharge Valve Wide Open With the steam feed tube to the trap chamber sealed, condensate flows through the condensate feed tube (from accumulation chamber) into the trap chamber. This sinks the inverted bucket, which opens the discharge valve, cycling the trap. Cycle Ending As the level of condensate in the accu- mulation chamber falls, the cup sealing the steam feed tube moves downward, opening a passage for steam to flow into trap chamber. Trap Closed As steam begins to flow through the accumulation chamber and up the steam feed tube under the inverted bucket in the trap chamber, the discharge valve closes tightly. Cycle About to Repeat As the level of condensate rises in the accumulation chamber, the cup floats up until it again seals the steam feed tube, and the cycle repeats.

Box 408, Three Rivers, MI 49093 – USA Phone: (269) 273-1415 Fax: (269) 278-6555 www.armstrong-intl.com Description Armstrong offers its 5000 Series forged chrome-moly steel traps for vertical installation with a choice of screwed, socketweld or flanged connections. A unique leverage system multiplies the force provided by the bucket to open the valve against system pressure. The mechanism is free-floating and has no fixed pivots to create wear or friction. Because the mechanism is located at the top of the trap, no dirt can collect on the orifice. Small particles of dirt are held in suspension until discharged by the full differential purging action when the bucket sinks, pulling the valve off the seat. The discharge orifice is surrounded by a water seal, preventing live steam loss. Automatic air venting is provided by a small vent hole in the bucket.This provides continuous automatic air and CO2 venting at steam temperature. Inverted bucket traps drain continuously, although discharging intermittently, to prevent condensate backup. They are also resistant to water hammer. Operation on Superheat. A normally operating bucket trap is filled with saturated steam and condensate. Superheated steam can enter only as fast as the steam inside can condense. As a result, the temperature of the trap is at (or slightly below) saturated steam temperature, regardless of the degree of superheat. Trap Selection. The pressure-containing parts of the steam trap should safely withstand the maximum pressure and temperature conditions of the system. For example, a trap is required for a 1,000 psig (68 bar) main at 950°F (510°C). The normal operating temperature of the trap will be about 546°F (286°C). A Model 5133G trap should be selected, even though several smaller traps are capable of handling the working pressure. For Superheat Service: 1. Don’t oversize the orifice; a restricted orifice may be advisable. 2. Specify a burnished valve and seat and an extended inlet tube and check valve. 3. Provide a drip leg of adequate diameter and length. 4. Provide a generous length (2'-3') of inlet piping, with the trap below the main. 5. Don’t insulate the trap or the inlet piping.

All working parts are stainless steel. Valve and seat are stainless steel, individually ground and lapped together in matched sets. Continuous air and CO2 venting Vent in top of bucket provides continuous automatic air and CO2 venting with no cooling lag or threat of air binding. Steam passing through vent is less than that required to compensate for radiation losses from the trap, so it’s not wasted. Purging action Snap opening of the valve creates a momentary pressure drop and turbulence in the unit drained. This breaks up films of condensate and air and speeds their flow to the trap. Virtually no steam loss Steam does not reach the water-sealed discharge valve. Dependable operation Simple, direct operation with nothing to stick, bind or clog. Only two moving parts— the valve lever and the bucket. Excellent operation against back pressure Since trap operation is governed by the difference in density of steam and water, back pressure in the return line has no effect on the ability of the trap to open for condensate and close against steam. Freedom from dirt problems Condensate flow under the bottom edge of the bucket keeps sediment and sludge in suspension until it is discharged with the condensate. Valve orifice opens wide and closes tightly. No buildup of dirt or close clearances to be affected by scale.Resistance to damage from water hammer Open bucket or float will not collapse as a result of water hammer. 360° universal 304 stainless steel connector Provides quick, easy in-line renewability along with all the proven advantages of an inverted bucket operation. Also available with optional IS-2 integral strainer connector with 20 x 20 mesh stainless steel strainer. Sealed, tamperproof 304-L stainless steel package Able to withstand freeze-ups without damage. The Armstrong stainless steel traps—Series 1000, Series U-1000, Series 1800 and Series 2000—have high resistance to damage from freeze-ups. They also offer high resistance to wear and corrosion for longer service reliability, and they provide continuous air venting. Armstrong stainless steel traps provide maximum ease and economy of installation, inspection or replacement. What’s more, an Armstrong stainless steel trap is the ideal solution for trapping applications such as tracer lines, steam mains, and heating and processing applications.
