Check valve

Tilting Disc Check Valve

Tilting Disc Check Valve on the pipeline media itself the flow generated by a force which open and close automatically,belonging to an automatic valve. check valve for pipeline system, its main function is to prevent the return of the media, to prevent the pump and driving motors reversing and container medium discharge. Check valve also can be used to give the pressure is higher than main system auxiliary system for supplying pipeline.

Wafer Single Plate Lift Check Valve

Single plate wafer lift check valves prevent reverse flow with disc movement that is parallel with the flow. With this design, the disc is always in the flow path. Discs are spring-loaded to assist in seating. These single plate wafer type lift check valves are bonnetless and are installed between flanges. The type of check valve disc has very short disc travel and responds very quickly to flow stoppage or reversal, thus minimizing the potential for water hammer. It is somewhat better than the ti…

Thin Type Wafer Single Disc Swing Check Valve

Check valves is usually installed in pipeline system,prevent medium from flowing back.check valve is automatic valve that it is opened and closed by pressure of fluid.In the past, we use H44 flange coupling swing type check valves&H44 flange coupling lift type check valve.Traditional check valves volume is big,strong resistance of fluid,Water-hammers pressure is high when valves close,repair and installation is inconvenient,service life is not long. Against the problem of traditional check va…
