Conbraco 10-616-32 Valve

The Conbraco 10-616-32 is a high-capacity hot water safety relief valve designed for commercial and industrial boiler applications. Engineered with a 1-1/4" Female NPT inlet and a 1-1/2" Female NPT outlet, this ASME Section IV certified valve is factory set at 140 PSI. It delivers a massive 9,607,000 BTU/hr relief capacity, ensuring critical overpressure protection for large-scale hydronic heating systems. The Apollo 10-600 series construction features a bronze body and stainless steel spring to resist corrosion and prevent seat sticking. This boiler pressure relief valve utilizes a high-volume flow design, making it an essential component for contractors maintaining compliance with local plumbing and mechanical codes. Its robust diaphragm creates a tight seal while allowing for consistent POP action during thermal expansion or system malfunctions. When replacing an existing 140 PSI relief valve, verify the BTU rating matches the maximum heat output of your boiler to prevent catastrophic vessel failure.

• High BTU Rating: Provides 9,607,000 BTU capacity for heavy-duty commercial boiler safety.
• Precise Pressure Management: Factory set and sealed at 140 PSI to ensure accurate discharge during overpressure events.
• Durable Construction: Bronze body and EPDM diaphragm offer long-term reliability in high-temperature applications.
• Standardized Plumbing: 1-1/4" x 1-1/2" NPT connections allow for straightforward integration into existing piping manifolds.

Is the Conbraco 10-616-32 suitable for steam service?
No, this specific model is designed strictly for hot water heating boilers and heat supply storage tanks. For steam applications, an ASME Section III or VIII valve rated for steam must be used.

What is the discharge capacity of this valve?
This valve is rated for 9,607,000 BTU/hr, which must exceed the boiler's gross output to meet safety standards.

Can this valve be mounted horizontally?
Standard HVACR practice and most local codes require these valves to be installed in a vertical position with the spindle upright to ensure proper drainage and operation.
