Silent check valve refers to a valve that automatically opens and closes the valve disc by the flow of the medium itself to prevent the backflow of the medium.

It is also called non-return valve, one-way valve, reverse flow valve, and back pressure valve. Check valve is an automatic valve.

Its main function is to prevent the backflow of the medium, prevent the pump and drive motor from reversing, and the release of the container medium.

Check valve can also be used to provide supply to the auxiliary system where the pressure may rise to exceed the system pressure.

Check valves can be mainly divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis).
