About Wafer Type Check Valve

The wafer check valve adopts a fluid-type design with small head loss; the internal spring can accelerate closing to achieve a silent effect; metal-to-metal ensures the reliability of sealing; and the installation space is small. It can be installed at the outlet of the water pump to avoid water hammer, water hammer sound and destructive impact, achieving the purpose of preventing backflow and protecting equipment. Widely used in water supply and drainage, fire protection, construction, HVAC, and industrial systems.

Check valve refers to a valve that relies on the flow of the medium itself to automatically open and close the valve disc to prevent the medium from flowing back. It is also called a check valve, one-way valve, reverse flow valve, and back pressure valve. The check valve is an automatic valve whose main function is to prevent the backflow of the medium, the reverse rotation of the pump and drive motor, and the release of the container medium. Check valves may also be used on lines supplying systems where the pressure may rise above the system pressure.

Wafer check valve is also called reverse flow valve. This type of valve automatically opens and closes by the force generated by the flow in the pipeline. It is an automatic universal valve.
