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 of the valve plate closed, the fluid pressure in turn make it open the spring Deformation quickly, this will protect the pipe from water hammer damage. Precautions for installation When placing the pipeline, pay attention to the flow direction of the wafer check valve and the flow direction of the fluid, and install it in a vertically placed pipeline. For horizontal piping, apply a clip-on check valve vertically. Use a bellows between the check valve and the butterfly valve. Do not connect it directly to other valves. Avoid the addition of fittings and obstructions over the operating radius of the valve plate. Do not install a reducer in front of or behind the wafer check valve. Pay attention to leaving enough space when mounting the wafer check valve near the bend. When attaching the wafer check valve at the pump outlet, at least six times the valve diameter is allowed out of the way to ensure that the disc is ultimately subjected to the fluid.
