Description
The Watts F278328 2″ Relief Valve is used to regulate pressurized circuits by discharging excess pressure when the system levels are above the 50 PSI mark to avoid possible damage. This is a mechanism based on an automatic opening of a spring-loaded valve that opens and closes automatically in the presence of high pressure 5,575,000 BTU, and returns to normal pressure in HVAC systems. It is installed at the required point of connection to the piping or vessel. It aids in safe operation, system integrity, and performance of the commercial and residential installations with high-capacity thermal loads.
