Trunnion ball valve, is a new generation of high-performance ball valves, suitable for long-distance pipeline and general industrial pipeline, its strength, safety, resistance to harsh environments and so on in the design of special considerations, applicable to a variety of corrosive and non-corrosive medium. It is compared with the floating ball valve, when working, the fluid pressure in front of the valve on the ball to generate the force all transferred to the bearing, will not make the ball to the seat, so the seat will not be subjected to excessive pressure, so the trunnion ball valve torque is small, the seat deformation is small, sealing performance is stable, long service life, suitable for high-pressure, large-diameter occasions.
