Floating Ball Valve
WOM’s Floating Ball Valves provide the user with an exceedingly reliable and proven design
offering maximum sealing against leaks. WOM’s Floating Ball Valves have separate ball and stem
design with a free floating ball preloaded between the seats during assembly.
When pressure enters the valve from the upstream side, the ball stem slot allows the ball to float
freely under pressure moving from its axis to seal on the downstream side, resulting in a pressure
assisted seal. The stem remains in the valve axis, enhancing stem seal performance for a tight seal
joint.
Floating Ball Valve
WOM Floating Ball Valves are suitable for the following applications:
• Oil and gas service with NACE and Non-Nace based material selections.
• Pharmaceutical and Chemical Industry based material selection.
• Standard temperature range of -20˚F to 250˚F
• Temperature range of -40˚F to 250˚F can be supplied on demand.

Floating Ball Valve
Features and Benefits
FIRE SAFE DESIGN
WOM Floating Ball Valves are designed to be in-
line fire safe. In the event of a fire, if the polymer
seats burn out, the ball touches the seat pocket
fillet in the body or end connector leading to a
metal seated sealing. Acceptable leakage rate
as per ISO 5208.
STEM DESIGN
• Blow out proof stem design
• Antistatic stem design ensures continuous
contact between the stem and the body
• The stem has multiple seals to prevent any
outside leakage
• Larger stem diameter with larger MAST values
as per ISO 5211
SEALS
• Seats are made from Nylatron and have a
multiple seal design providing enhanced sealing
performance than that of other valves in the
market
• A tapered stem thrust washer made from
reinforced PTFE acts as primary stem seal joint
• Thrust washer reduces friction and hence
reduces torque
• Body and end connector joint o-ring provides
tight static seal joint
• Closed diametrical clearance between ball
outside diameter and body inside diameter
leads to less pressure build up within body cavity
