Check Valve Working principle
The role of the check valve is to allow the medium to flow in one direction only and to stop the flow in the opposite direction. Usually, this valve works automatically, with the valve flap opening under the pressure of fluid flowing in one direction; fluid flowing in the opposite direction is cut off by fluid pressure, and the self-weight of the valve flap acting on the valve seat.
When installing the check valve, please note that the direction of fluid flow should be consistent with the arrow pointing to the valve body.
