API Carbon Steel Flanged Trunnion Ball Valve

The side entry trunnion mounted ball valve has been designed two piece body type or three piece body type and with two floating seats, which are movable under the pressure of medium. Under the bottom of seats, seat pre-loading springs are positioned to ensure two floating seats can attach the ball’s surface tightly, other more, pressure of medium also can push seats to attach ball tightly to ensure sealing more reliable. The trunnion ball valve is equipped with a movable seat seal ring which can generate displacement under the pressure of medium. In case that any medium pressure exists, the pressure will press the valve seat seal ring onto the ball tightly, guaranteeing the sealing performance of the ball valve.
Product Details

API  Carbon Steel Flanged Trunnion Ball Valve

Main Features:

The ball of the ball valve is fixed and does not produce movement after compression. Fixed ball valves are equipped with floating seat, after being subjected to medium pressure, the seat produces movement, so that the sealing ring is pressed tightly on the ball to ensure the seal. Usually on top of the ball, the lower shaft is equipped with bearings, the operating torsion distance is small, suitable for high pressure and large caliber valves. In order to reduce the operating torque of the ball valve and increase the reliability of the seal, oil seal ball valve has appeared again in recent years, not only in the sealing surface pressure injection special lubricating oil, to form a layer of oil film, that is, enhance the sealing, but also reduce the operating torque, more suitable for high pressure large caliber ball valve.
