Description
The Watts F275824 1-1/4″ Pressure Relief Valve 2,459,000 BTU 174 A 50 PSI is a pressure-regulating security component used for boilers and hydronic systems requiring controlled pressure discharge. It opens automatically when internal pressure rises beyond the specified limit and it allows the excess fluid into the system. This valve is applied in high-capacity heating equipment, commercial boilers and compatible systems where pressure management is essential for normal operation in HVAC systems. This mechanism supports maintaining system balance, protects connected equipment from overpressure conditions and supports circulation throughout the heating process.
