The Watts 174A Series bronze boiler pressure relief valve is specifically designed to safeguard hot water space heating boilers by preventing excessive pressure buildup. This essential component ensures the safe operation of your boiler system. The valve features a 3/4 inch NPTF female inlet and outlet, with a pressure relief setpoint of 30 psi. It is constructed from durable bronze and incorporates a non-metallic disc-to-metal seating for reliable performance. Additionally, the valve includes a test lever for easy manual testing. For enhanced monitoring, the valve is equipped with a nonrestrictive discharge drain line flood sensor that integrates with SentryPlus Alert® technology. This system detects excessive water discharges from the relief valve, although activation of the sensor requires the purchase of a separate activation kit.
