Check valve is a type of valve which open or close the valve disc rely on the medium flow itself.
The check valve disc will open when the pressure of stem bottom exceed the stem above and the spring. The check valve disc will close when the two pressure are equalled.
So that the flow goes one way in the pipeline, and prevent the fluid flowingback, avoid the accidents.
