Aluminum Bronze body Muffle/ Silent Lift Check Valve(H71)

Main Features

The valve is opened/closed by the valve disc moving in a direction parallel to the valve seat hole axis and can only be installed on horizontal pipelines with the major function of preventing medium backflow when shutting down the pump and maintaining the water column required by pumping.For H71 h, the main function of the clamping check valve is small water hammer pressure, short disc stroke, light disc, spring-assisted closure and fast valve closing speed. The disc of the clamping and lifting check valve is disc-shaped and rotates around the rotating shaft of the valve seat channel, and the flow resistance of the clamping and lifting check valve is smaller than that of the butterfly check valve, which is suitable for large caliber situations with low velocity and irregular flow. The purpose is to prevent the medium from stopping flow or backflow to weaken the hydraulic impact.
