Ball Check Valve refers to the valve that automatically opens and closes the valve disc depending on the flow of the medium itself, which is used to prevent the flow back of the medium. It is also called check valve, one-way valve, counter-flow valve and back pressure valve. Check valve is an automatic valve, its main role is to prevent medium backflow, prevent pump and drive motor reversal, as well as container media release. Check valves can also be used to supply lines in which the pressure may rise to an auxiliary system that exceeds the 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).
