Aluminum/Nylon Pressure Relief Valve, 300PSI, 3/4"FPT

Aluminum/Nylon Pressure Relief Valve, 300PSI, 3/4"FPT

The 846034 Aluminum/Nylon Pressure Relief Valve (300 PSI, 3/4" FPT) is a diaphragm-style relief valve designed to help you maintain consistent spray line pressure by diverting excess liquid back to the source when pressure rises. Built with an aluminum and nylon construction, it supports up to 300 PSI and 70 GPM, and includes an open gauge port so you can optionally add a pressure gauge for easy monitoring.
