Application
This type of check valves are used to stainless steel pipe line system, in order to prevent the fluid flowing back. It is used in food, beverage , wine, oil, cosmetics, pharmaceutical and chemical industries.
Work principle
Check valve is type of valve which open or close the valve disc 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 will close when the two pressure are equaled. So that the flow goes one way in the pipeline, and prevent the fluid flowing back, avoid the accidents.
