Cast Steel Check Valve
Introduction:
Check valve refers to the valve that automatically opens and closes the valve flap depending on the flow of the medium itself to prevent the backflow of the medium, also known as check valve, one-way valve, reverse flow valve, and back pressure valve.
Function:
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 the driving motor, and the discharge of the medium in the container. Check valves may also be used on lines supplying auxiliary systems where pressure may rise above 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).
