Product Description

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. 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 open automatically.
