Spring Check Valve – Female/Female
A spring check valve utilizes a spring and disc to close the valve and prevent fluid flow reversal. Because of spring-assisted closure, spring-loaded check valves close before any backflow through the valve. These valves are popular because of their versatility and protection against backflow.
