Conbraco 10-617-12 Valve

The Conbraco 10-617-12 is a heavy-duty hot water high capacity pressure relief valve designed specifically for large-scale hydronic heating systems and commercial boilers. Engineered as an ASME Section IV certified safety device, this valve features a massive 6,252,000 BTU capacity and is factory-calibrated at a 60 PSI set pressure. The 10-617-12 serves as the direct replacement for 0537-G01-HM0060, providing seamless integration for technicians upgrading existing relief systems. Built with a robust ASTM B584 bronze body and a silicone seat, it employs a diaphragm-isolated spring chamber to prevent corrosive media from contacting the internal spring, ensuring consistent performance up to 250°F. The 1-1/2" Female NPT inlet and 2" Female NPT oversize outlet are designed to reduce backpressure and facilitate maximum discharge flow during overpressure events. This industrial-grade relief valve offers the high-volume protection necessary for high-density commercial boilers and thermal expansion management.

• Extreme High Capacity: Delivers a 6,252,000 BTU/HR rating, ideal for large commercial and industrial heating boilers.
• Corrosion-Resistant Engineering: Features a bronze body and a fabric-reinforced molded diaphragm to isolate the spring from system water.
• Oversize Discharge: The 2" FNPT outlet allows for rapid pressure dissipation, preventing system damage during failure states.
• ASME HV Certified: Rated at 90% of actual capacity at 10% overpressure, meeting strict National Board safety standards.
• Versatile Replacement: Explicitly designed as a direct drop-in for the 0537-G01-HM0060 model.

What is the maximum operating temperature for the 10-617-12?
This valve is rated for a maximum temperature of 250°F (121°C), making it suitable for standard and high-temperature hydronic heating applications.

Can this valve be used for steam applications?
No, the 10-600 series is specifically certified for ASME Section IV Hot Water service. It is not intended for steam boiler protection.

Why is the outlet larger than the inlet?
The 2" NPT outlet is expanded to accommodate the high volume of water discharge and steam flash-off required to maintain system safety without creating backpressure at the seat.
