Description:
Sanitary check valve is a spring check valve with different connection ends , and is also named “non-return valve”, the check valve function is to avoid the fluid flowing back and keep the fluids always in one direction flow.
In each pipeline, the check valve is required to be installed to keep the flow in one direction. Through the medium brings flow pressure by itself, the valve close and open automatically.
The body of sanitary check valve is usually made of stainless steel forged material which ensure no sand holes, no burrs and stable structure.
Application
Sanitary check valves are widely used to prevent the liquid flowing from revering direction.The check valves can ensure the fluid flow in one way direction and inhibit the fluid flow back.
It is suitable for use in the food, beverage, biotech, pharmaceutical, and other hygienic applications.
Working Principle
The check valve ( non return valve) is normally working automatically, it is closed if no media flow. When the pressure of the fluid is heavier than the pressure of the spring, the check valve opens automatically. When the two pressure are equalized, the valve closes. A stronger counter-pressure allows the valve to close.
