The wafer check valve is a universal one-way fluid valve. Its light weight, small size, easy to install between the flanges, the valve consists of two semi-circular spring and the plate surface, the pin is fixed on the valve body spring deformation valve plate is closed, the fluid pressure and make it open the spring Deformation quickly, this will protect the pipe from water hammer damage. Installation Precautions When placing the pipe, make sure the direction of flow of the wafer check valve is the same as that of the fluid. Install the pipe in a vertically placed pipe. For horizontally placed pipe clamps, use a telescopic pipe vertically between the check valve and the butterfly valve, and do not connect it directly to other valves within the operating radius of the valve plate to avoid Add fittings and obstructions. Do not install a reducer in front of or behind the wafer check valve When mounting a wafer check valve near the bend, care should be taken that sufficient space is left for the wafer check valve to be installed at the pump outlet, Leave at least six times the valve diameter space to ensure that the disc is ultimately subjected to the fluid
