1/2″ Spring Check Valve — Brass

Spring Check Valve

• 1/2″ FIP
• Lead Free Brass
• O-Ring Seal
• Stainless Steel Spring

The disc on a spring check valve is held closed by the tension of a spring inside of the valve. Pressure on the inlet pushes against the disc, overcoming the spring and allowing flow. The disc cannot open when pressure is applied from the wrong direction. Spring checks can be installed in any orientation and provide a greater degree of backflow prevention than a swing check. They may create greater flow resistance, but tend to be quieter than swing checks.
