Trunnion Ball Valve - API 6D

Trunnion Ball Valve Overview # Trunnion Ball Valve Features: 1) Anti-fire safe design: API 6FA, API607 2) Anti-static device The static-conduction spring is set between the stem and the ball, the stem and the body. Thus static electricity is conducted to ground    and system safety is secured. 3) Anti-blow out design 4) Free leakage of body Sealed construction The connective position of valve body and bonnet is double sealed by gasket and O-ring, on this base, such factors as fire, high temperature, shock and uneven opening or closing of the torque all can’t induce external leakage 5) Low torque in operation 6) Double block&bleed(DBB) 7) Emergency sealing 8) Automatic body cavity relief When the body pressure going up un-normally as the unstable factor, the trunnion ball valve downstream seat will be pushed by un-normal pressure, and the release the un-normally pressure automatically, it doesn’t dama…
