The Conbraco Industries 10-615-09 is a high-capacity hot water pressure relief valve engineered to deliver dependable overpressure protection in demanding hydronic heating and hot water systems. With a factory-set relief pressure of 45 PSI and an impressive 2,114,000 BTU capacity rating, this valve is built to handle the rigorous demands of commercial and high-output residential boiler and water heater applications.
The 10-615-09 features a 1″ Female NPT inlet connection and a larger 1-1/4″ Female NPT outlet, a design that promotes efficient discharge flow and helps prevent back pressure buildup during a relief event.
