Industrial Check valve is typically used for the outlet of the pump. Check valves are generally divided into lift type, swing type, butterfly type and diaphragm type. The industrial check valve is a valves that automatically prevents the fluid from flowing backwards. The industrial valve flap (disc) of the check valve is opened under fluid pressure, and the fluid flows from the inlet side to the outlet side.
When the inlet side pressure is lower than the outlet side, the valve disc (flap) is automatically closed under the influence of the fluid pressure difference and its own gravity to prevent the fluid from flowing backward.
