Trunnion Ball Valves
For pipeline use and general processes Unlike floating-ball designs that allow the ball to move with line-flow conditions, a trunnion design with coil spring-loaded seats prevents particulate matter from getting between the seat and ball contact area, eliminating premature seat leakage, increasing cycle life, reducing down time and lost production.
