Trunnion Mounted Ball Valve is a new generation of high-performance ball valves, it is compared with the floating ball valve, the fluid pressure in front of the valve on the ball to generate all the force transferred to the bearings, the ball will not move to the valve seat, so the Trunnion Mounted Ball Valve of the torque is small, the seat deformation is small, the sealing performance is stable, long service life, suitable for high-pressure, large caliber pipeline, long-distance pipeline and general industrial pipelines.

The structural feature of the double eccentric butterfly valve is that the valve stem axis deviates from the center of the butterfly plate and from the center of the body. The double eccentric effect allows the butterfly plate to quickly detach from the valve seat after the valve is opened, greatly eliminating unnecessary excessive compression and scratching between the butterfly plate and the valve seat, reducing the opening distance, lowering wear, and improving the service life of the valve seat. Mainly suitable for water supply and drainage systems in water plants, power plants, steel mills, papermaking, chemical industry, catering, etc., especially suitable for water supply pipelines.
