ProLine Series 1 in. Solvent x Solvent PVC Check Valve

The PVC Check Valve permits water to flow in one direction within a line with the ProLine SERIES 1 in. Solvent x Solvent PVC Check Valve. It acts as a backflow prevention device to prevent water from backing up into a municipal, residential or commercial water supply. This valve is built using a steel spring-loaded poppet to keep the valve shut until the needed pressure is reached to open the valve.
