Lift & Swing Check Valve

Internally threaded 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 backflow of the medium. 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 auxiliary systems where the pressure may rise above 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). This type of valve should generally be installed horizontally in pipelines.
