Flange Stainless Steel DN150 Check Valve
Flanged Check Valves Introduction
Flange check valve is a valve that automatically opens and closes the valve disc by the flow of the medium itself to prevent the medium from flowing back. It is also called a non-return valve, a one-way valve, a reverse flow valve, and a back pressure valve. A check valve is an automatic valve. Its main function is to prevent the medium from flowing back, to prevent the pump and the drive motor from reversing, and to release the container medium. The check valve can also be used on the pipeline that provides 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).
