Product overview
The clamp lift check valve refers to the valve which automatically opens and closes the disc depending on the flow of the medium itself, and is used to prevent the medium backflow, also known as the check valve, one-way valve, counterflow valve, and back pressure valve. Check valve is an automatic valve. Its main function is to prevent medium backflow, reverse pump and drive motor, and release of container medium. Check valves can also be used in pipelines to supply auxiliary systems where pressure may rise above system pressure. Check valves can be divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis).
