Stainless Steel Sanitary Double-union Non Return Valve for Liquid Control

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.
