Fixed ball valve

Fixed ball Instrument valve, is a new generation of high-performance ball valve, suitable for long-distance pipelines and general industrial pipeline, its strength, safety, resistance to harsh environments and so on in the design of special consideration, suitable for all kinds of corrosive and non corrosive media. It is compared, and the floating ball work force, fluid pressure before the Instrument valves is generated in the sphere of all transferred to the bearing, not to move the ball to the seat, which seat would not put too much pressure, so the torque of the fixed ball valve seat seal small, small deformation, stable performance, long service life, suitable for high pressure, large caliber occasions. Advanced spring pre seat assembly, self tight characteristic, and the upstream seal. Each valve has two valve seats, each direction can be sealed, so the installation does not restrict the flow is bidirectional. This valve is usually installed horizontally.
Fixed ball valve has two style and three type two body structure, the flange bolts, sealed with PTFE inserts into the stainless steel ring, steel ring is arranged at the rear part of the spring to ensure the seat close to the ball, keep the seal. The upper and the lower valve rod are provided with PTFE bearings, reducing friction, labor-saving operation, a small shaft bottom is provided with an adjusting plate, ensure the ball and the sealing ring is connected with a position. Full size: the valve flow aperture consistent with the pipeline diameter, for pipeline cleaning.
