Description
The Watts F121470 3/4″ FNPT pressure relief valve for use in HVAC systems. As is explicitly designed for control of pressure build-up beyond design limits due to causes such as expansion due to high temperatures, fluctuation due to pump operation, or system faults. This valve works through opening automatically once pressure rises and crosses the limit of 75 PSI. This minimizes any possible harm to essential parts of a system such as boilers, heat exchangers as well as piping systems. The ability of the valve reaches 1,320,000 BTU to provide proper pressure for most residential and commercial HVAC systems.
