Description
The Watts F384242 is a heavy-duty 2″ Series 740 iron boiler pressure relief valve engineered to safeguard hydronic heating systems from dangerous overpressure conditions. Factory-set at 45 psi, this valve automatically opens to discharge excess pressure, protecting your boiler and connected piping from damage or failure. The expanded outlet design allows for greater discharge flow capacity, making it well-suited for larger boiler installations where rapid pressure relief is critical.
A standout feature of the F384242 is the included discharge line flood sensor, which adds an extra layer of protection by detecting any water discharge from the relief valve outlet — alerting building owners or technicians to an overpressure event before water damage can occur. This integrated safety feature makes the F384242 a smart choice for commercial and residential boiler rooms alike.
