The wafer check valve relies on the pressure generated by the fluid in the pipeline to open or close. It is an automatic valve, which can be used to avoid backflow of the medium.
The wafer check valve does not have handles and other parts to control the device, so it is an automatic valve. When the fluid flows in one direction, pressure will be generated under the impact of the fluid, which will open the valve flap. When the fluid flows in the opposite direction, the valve flap will avoid closing, thereby cutting off the fluid.
