API 6D Welded Body Trunnion Mounted BallValve is widely used in long transmission pipe of oil and gas because thewelded body construction prevents the Trunnion Ball Valve fromleaking risk through valve body.
The trunnion mounted ball valve is onekind of widely used oil and gas industry valves. The API 6D Welded BodyTrunnion Mounted Ball Valve has two floating seats assembling with springsloaded, in which the ball is fixed at two pivot points, and the processpressure pushes the upstream seat against the trunnion ball's sealing surface.This design applies continuous pressure against a trunnion mounted ball afterthe ball is installed.
