Fixed ball valve is a new generation of high-performance ball valve, suitable for long-distance pipelines and general industrial pipelines. Its strength, safety, and harsh environment resistance are specially considered in the design, and it is suitable for various corrosive and non-corrosive media. .
Compared with the floating ball valve, when working, the force generated by the fluid pressure in front of the valve on the ball is all transmitted to the bearing, and the ball will not move to the valve seat, so the valve seat will not bear excessive pressure, so the fixed ball valve The torque 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 high pressure and large diameter occasions. The advanced spring pre-valve seat assembly has self-tightening characteristics to achieve upstream sealing. Each valve has two valve seats, which can be sealed in each direction, so the installation has no flow direction restriction and is two-way. This valve is generally installed horizontally.
The fixed ball valve has two-piece and three-piece valve body structures. The middle flange is connected by bolts. The seal adopts reinforced polytetrafluoroethylene inlaid into the stainless steel ring. There is no spring behind the steel ring to ensure that the valve seat is tightly attached to the ball and keeps seal.
