Trunnion Ball valve is straight-through flow valves which provide positive shutoff with minimal pressure drop and flow turbulence. The barrier to flow is a ball which is rotated 90 degrees to the direction of flow. The trunnion 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.
