ProLine 1/2” Brass Swing Check Valve 200 PSI 101-003NL

The ProLine heavy duty, brass swing check valve, only allows water to flow in one direction, acting as a backflow prevention device. It keeps contaminated water from flowing back into the main water supply and prevents backflow from wells and boiler systems. The side tap allows drainage from the non-pressure side when the cap is removed. Install in line with a half inch female threaded connection. Compatible with iron pipe connection types. Maximum operating pressure rating of 200PSI.
