The HC41X energy-saving shuttle check valve is mainly used in water supply systems. It is vertically installed in pipelines and can be lifted or lowered by the pressure difference within the system and the weight of the valve disc. It automatically prevents the backflow of medium water and ensures the normal operation and use of pipelines.
The HQ41X ball type ball check valve adopts a rubber wrapped ball as the valve disc. Under the action of the medium, it can roll up, down, left and right on the integral slide inside the valve body to open or close the valve. Silent closure, no water hammer generated, good sealing performance. The valve body adopts a full water flow channel, with h1
