Conbraco 10-616-16 Valve

The Conbraco 10-616-16 is a high-capacity ASME Section IV hot water relief valve designed for heavy-duty protection in commercial boiler systems and large-scale hydronic heating applications. Engineered for reliability, this 1-1/4" NPT inlet x 1-1/2" NPT outlet valve features a factory-set pressure of 80 PSI and a substantial discharge capacity of 5,849,000 BTU/hr. The 10-600 series architecture utilizes a bronze body and a Teflon-faced EPDM diaphragm to prevent the sealing surface from sticking, ensuring overpressure protection even after long periods of inactivity. This high-capacity pressure relief valve is essential for maintaining system integrity by venting excess pressure during thermal expansion or control failure. Its rugged construction and precise pressure relief settings make it a standard choice for HVACR contractors servicing high-output water heating equipment where ASME code compliance is mandatory.

• ASME Section IV Certified: National Board certified for high-pressure hot water heating boilers and heat recovery systems.
• Superior HVAC Flow Capacity: Rated at over 5.8 million BTU to handle industrial-grade thermal loads.
• Durable Sealing: Features a reinforced EPDM diaphragm and silicone seat to resist heat degradation and chemical scaling.
• Standard NPT Connections: Facilitates straightforward integration with existing 1.25 x 1.5 boiler piping headers.

Common Questions

What is the maximum operating temperature for this valve?
This 10-600 series valve is typically rated for a maximum temperature of 250°F, making it suitable for standard and high-temperature hydronic loops.

Can this valve be used for steam applications?
No, the 10-616-16 is specifically designed and ASME rated for hot water services only; steam applications require a different series with appropriate lift characteristics.

How should the discharge piping be sized for this 80 PSI relief valve?
The discharge line must be at least the same diameter as the valve outlet (1-1/2") and should be piped to a safe point of discharge to prevent injury or equipment damage during an overpressure event.
