Description
The Watts F384442 Boiler Pressure Relief Valve 2″ FNPT X 2-1/2″ FNPT 10,700,000 BTU 75 PSI 740 is a protection component that discharges excess internal pressure when operating limits are exceeded. It responds to rising pressure through a spring-loaded internal mechanism that opens the outlet path once the calibrated threshold is reached preventing overpressure conditions during thermal load changes. After pressure stabilizes the valve reseats automatically to restore sealed operation. Installed on the outlet line of heating equipment, it integrates into HVAC systems to protect connected components and maintain controlled pressure levels during continuous heating cycles.
