Main features: The force generated by the fluid pressure in front of the valve on the ball is all transmitted to the bearing, which will not cause the ball to move towards the valve seat, so the valve seat will not bear excessive pressure. Therefore, the torque of the fixed ball valve is small, the deformation of the valve seat is small, the sealing performance is stable, and the service life is long. It is suitable for long-distance pipelines and general industrial pipelines. Its strength, safety, and resistance to harsh environments have been specially considered in the design, and it is suitable for various corrosive and non corrosive media.
