Check valve is a type of valve which opens and closes relying on the medium flow itself. The check valve disc will open when the pressure of stem bottom exceeds the stem above. The check valve disc will close when the two pressure are equal. So that the flow goes one way in the pipeline, and prevents the fluid from flowing back to avoid the accident.It needs pressure about 6kpa to open the valve if the check valve is installed in a vertical pipe. Maximum pressure for conveying material is 1000Kpa. The proper temperature scope is -10°C-140°C.Widely used in various processes throughout the sanitary industry, these sanitary check valve are safe and highly reliable.
