Conbraco 10-616-01 Valve

The Conbraco 10-616-01 Valve is an engineered ASME Section IV safety relief solution specifically designed for high-capacity hot water heating boilers and supply systems. Featuring a 1-1/4" Female NPT inlet and an expanded 1-1/2" Female NPT outlet, this 15 PSI relief valve provides a high-flow discharge path to manage pressure spikes in large-scale hydronic systems. With a certified 1,777,000 BTU capacity, it is built with a rugged ASTM B584 bronze body and a corrosion-resistant plated alloy steel spring. To ensure long-term reliability in demanding HVACR environments, the valve utilizes a fabric-reinforced diaphragm that completely isolates the spring chamber from the water media, preventing mineral buildup and corrosive attack. This hot water pressure relief valve also includes a silicone seat for tight shut-off and an elevated seat design that promotes superior drainage after discharge. For technicians managing commercial boiler safety, the 10-616-01 offers the necessary National Board capacity certified performance for critical overpressure protection.

• High BTU Rating: Provides a robust 1,777,000 BTU capacity, meeting high-output commercial heating system requirements.
• Superior Isolation: The fabric reinforced molded diaphragm keeps water away from the spring, maintaining consistent set-point accuracy.
• Expanded Discharge: The 1-1/2" expanded outlet allows for higher volume relief compared to standard 1-1/4" units, minimizing backpressure during operation.
• Compliance Ready: Fully ASME Section IV certified and National Board rated, ensuring code compliance for hot water heating systems.
• Durable Construction: Features a corrosion-resistant bronze body and a silicone seat rated for temperatures up to 250°F.

What is the maximum operating temperature for this valve?
The Conbraco 10-616-01 is engineered to handle media temperatures up to 250°F (121°C), making it compatible with most standard and high-temperature hydronic boiler applications.

Is the 10-616-01 National Board certified?
Yes, the entire 10-600 series pressure range is National Board capacity certified and adheres to ASME Section IV specifications for heating boilers and systems.

Can this relief valve be used on steam boilers?
No, this specific model is a hot water high capacity pressure relief valve. For steam applications, ensure you select a valve rated specifically for steam service and Section I or Section IV steam requirements.
