A trunnion-mounted valve determines that the ball is compelled by bearing and only permitted to rotate. Benefits of trunnion ball design are the more moderate running torque, efficiency of performance, reduced seat wear. Superior sealing performance at both high and low pressure.
Benefits:
More profound operating torque.
The efficiency of operation.
Minimized seat wear.
Trunnion Mounted Ball Valves
A trunnion ball valve is a kind of quarter-turn valve which utilizes a hollow, perforated, and fixed/supported ball to control flow
within it. The ball rotates without moving on the horizontal axis, whereas seats are floating.
