Pneumatic fixed ball valve

Pneumatic fixed ball valve
Overview
Pneumatic fixed ball valve is a new generation of high-performance ball valve, suitable for long-distance pipelines and general industrial pipelines, with its strength, safety, resistance to harsh environments, etc. Special considerations have been made in the design and are suitable for a variety of corrosive and non-corrosive media. Compared with the floating ball valve, when it works, 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 toward the valve seat. Therefore, the valve seat has small deformation, stable sealing performance, long service life, and is suitable for Suitable for high pressure and large diameter situations. 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 there is no flow restriction when installed, and it is bidirectional. This valve has two body structures: two-piece and three-piece. The middle flange is connected with bolts. The seal is made of reinforced polytetrafluoroethylene embedded in a stainless steel ring. There is a spring at the back of the steel ring to ensure that the valve seat is close to the ball. Keep it sealed. The upper and lower valve stems are equipped with bearings to reduce friction and save effort in operation. There is no adjustment piece at the bottom of the small shaft to ensure the joint position between the ball and the sealing ring. The full-bore structure is adopted to make the valve flow hole consistent with the inner diameter of the pipeline to facilitate pipeline cleaning.
