This type of check valves are used to stainless steel pipe system,
in order to prevent the fouid flowing back.
Stainless Steel Sanitary Check Valve(304/304L/316L)
Work Principle:
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.
Various standards of valves can be provided to clients:
DIN, 3A, SMS, ISO/IDF, BS/RJT, ASME/BPE etc.
