Conbraco 10-615-01 Relief Valve

The Conbraco 10-615-01 is a high-capacity ASME Section IV safety relief valve designed specifically for large-scale hot water heating boilers and heat recovery systems. Engineered with a 1" FNPT inlet and a 1-1/4" FNPT outlet, this valve provides a substantial 1,027,000 BTU/hr relief capacity when set at its standard 15 PSI relief pressure. The 10-600 series utilizes a non-stick Teflon-faced EPDM diaphragm and a high-volume BTU discharge design, ensuring rapid pressure stabilization and preventing seat stickage during critical overpressure events. For contractors managing hydronic heating systems, the bronze body construction and stainless steel springs offer the durability required for commercial mechanical rooms. This boiler safety valve features a top-guided design and a standard zinc-plated steel lever for manual testing, making it a reliable choice for maintaining compliance and system integrity in professional HVACR applications.

• High BTU Rating: Delivers a 1,027,000 BTU/hr discharge capacity, ideal for high-output commercial boilers.
• Corrosion Resistance: Features a rugged bronze body and stainless steel internal springs to withstand harsh hydronic environments.
• Positive Seal: The EPDM diaphragm provides a bubble-tight seal and reliable shut-off after pressure release.
• ASME Certified: Built to meet strict National Board and ASME Section IV standards for safety and performance.
