Conbraco 10-417-15 Relief Valve

The Conbraco 10-417-15 is a high-capacity hot water relief valve engineered specifically for hydronic heating systems and boiler protection. Featuring a 3/4" MNPT inlet and a 3/4" FNPT outlet, this ASME Section IV certified safety valve is factory-set at 75 PSI to ensure reliable overpressure protection. With a substantial discharge capacity of 972,000 BTU/hr, the 10-417-15 is built for durability with a corrosion-resistant bronze body (ASTM B584) and a stainless steel spring. The integrated silicone seat provides a bubble-tight seal that withstands thermal cycling up to a maximum temperature of 250°F. Contractors rely on this Apollo Valves series for its precision and compliance with safety relief valve standards in commercial and residential boiler applications. Integration into existing piping is straightforward due to the standard NPT threading, making it a staple for maintaining boiler system safety.
