The opening and closing principle of check valve is the same as that of lifting check valve, which also depends on the action of fluid pressure and the weight of the valve disc. The difference is that the opening and closing way of the valve disc is rotating motion rather than moving up and down, and the inlet direction of the fluid should be on the side that can impact the rotation of the valve disc.
The closing part of check valve by dual plates check valve supplier is a disc or disc equivalent to the diameter of the pipeline. It is suspended in the valve chamber.
