It is also called a non-return valve, a one-way valve, a reverse flow valve and a back pressure valve. The check valve is an automatic valve. Its main function is to prevent the backflow of the medium, the reversal of the pump and the drive motor, and the discharge of the container medium. The check valve can also be used on pipelines that provide supply to auxiliary systems where the pressure may rise to exceed the system pressure. Existing check valves cannot detect water quality. Therefore, an internally threaded swing valve is particularly needed.
