bare stem 6'' 900LB A105 trunnion mounted full port RF ball valve
- Valve type: Ball valve
- Port size:6''
- Pressure:900LB
- Material: A105
- End: RF
- Operation: bare stem
- Application: Stem
- Medium : Stem
- Working temperature: high pressure
Features:
Sideentry design
Anti Blow-out Stem:The stem is made separately from the ball. The lower end of the stem isdesigned
withan integral shoulder to be blowout-proof.
Anti-staticDevice: The Antistatic Device is a standard feature of the Cowinns ball valve.
Firesafe design:
The trunnion ballvalve feature : On a ball with a free floating ball, the ball isforced against the down-stream
seat bythe fluid pressure acting on the entire surface of the ball.
Sincethe resulting torque is a product of the friction force and the seat-ball
contactradius, the break to open torque increases substantially with the
increasingof the differential pressure and/or the size of the valve.
Thismeans that above a certain size and/or a certain differential pressure the
requiredbreak to open torque will be so high that it will be impossible to
operatethe valve.
