The wafer check valve is a general one-way fluid valve. It is light in weight, small in volume, easy to install between flanges, and consists of two semicircular springs and plate surfaces inside the valve. The valve plate is closed by spring deformation fixed on the valve body with a pin, and the fluid pressure makes the deformation of the open spring very fast, which can protect the pipe from the damage of the water hammer.
