Product introduction:

ANSI swing check valve is to rely on the media itself, the flow of automatic open and close the valve to prevent the media backflow valve, also known as the non-return valve, check valve, reversing valve, and back pressure valve. Check valve is an automatic valve, the main role is to prevent the backflow medium to prevent the pump and drive motor reversal, as well as the container medium discharge. Check valves can also be used to the pressure may rise to exceed the system pressure of the auxiliary system supply pipeline. Check valves can be divided into swing type check valves (depending on the focus of rotation) and lift check valve (along the axis of movement).
