Conbraco 10-605-25 Relief Valve

The Conbraco 10-605-25 is a high-capacity ASME Section IV hot water relief valve designed for heavy-duty commercial and industrial boiler applications. Featuring a 1-inch FNPT inlet and a 1-inch FNPT outlet, this safety device is factory set at 125 PSI to ensure reliable overpressure protection. With a substantial 4,272,000 BTU capacity, it manages high-volume thermal expansion and steam flashing efficiently. The construction utilizes a bronze body and a silicone seat to prevent galling and ensure a positive seal after actuation. This HVAC pressure relief valve is essential for contractors maintaining large-scale hydronic heating systems where precise boiler safety valve settings are non-negotiable. Its high BTU rating makes it a standard choice for hot water boiler overpressure protection, providing a rugged solution for high-demand environments. Proper installation of this Apollo relief valve ensures system integrity and compliance with rigorous mechanical codes without compromising flow rates during discharge.
