Watts F274596 3/4" Pressure Relief Valve 70 PSI

The Watts F274596 3/4" Pressure Relief Valve is used to release excess pressure from fluid systems when internal levels exceed the set safety limit. Controlled pressure regulation is required to protect connected equipment from overpressure conditions in HVAC systems. Installed in piping and heating assemblies, the valve automatically opens at 70 PSI to discharge excess buildup and returns to a closed position once normal conditions are restored. As a safety component, it maintains stable system pressure and supports operation during continuous use.
