The working principle of the Cast Iron Check Valve:

A -- The valve disc of Swing Flex Check Valve is closed when the medium in the pipeline flows normally, and the medium is sealed through the sealing ring between the valve disc and the valve body to prevent the medium from leaking.

B --When the medium in the pipeline countercurrent, the valve disc of 3 Swing Check Valve will automatically open, thus cutting off the entry of the countercurrent medium, to ensure the normal operation of the pipeline.

C --Adjusting bolts can adjust the opening Angle of the disc to control the flow of fluid.

D --The opening and closing of the valve disc is caused by the joint action of the weight of the valve disc itself and the pressure of the medium, so that the valve disc automatically closes or opens.

E --The flanged swing check valve also has an automatic compensation function, which can automatically compensate the temperature change and pressure change of the medium in the pipeline to ensure the normal operation of the valve.
