Working Principle:
Check valve is a type of valve which open or close reply on the medium flow itself. The check valve disc will open when the pressure of stem bottom exceed the stem above.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 flowing back ,avoid the accidents.
Material:
steel parts: 304 stainless steel, stainless steel 316L.
Seal: silicone rubber Material (VMQ) fluoroelastomer (FPM) ,EPDM
Technical Data:
If the check valves are installed in a vertical pipe, it needs approximately equal pressure 6Kpa to open. Maximum pressure for conveying material is 1000Kpa,.Using temperature scope for – 10 ℃ – 140 ℃
