Conbraco 10-614-12 Valve

The Conbraco 10-614-12 (also known as the Apollo 10-614-12) is a high-capacity ASME Section IV safety relief valve designed specifically for the protection of hot water heating boilers and large-scale hydraulic systems. Featuring a 3/4" FNPT inlet and an oversized 1" FNPT outlet, this valve is factory set at 60 PSI to manage high-volume discharge requirements. It delivers a substantial 1,641,000 BTU/hr capacity, making it a critical component for preventing over-pressurization due to control failure. The ASTM B584 bronze body and spring cage ensure long-term corrosion resistance, while the silicone seat provides a positive seal to prevent weeping. A fabric-reinforced molded diaphragm isolates the plated alloy steel spring from the process media at all times, preventing scale buildup and spring degradation. This National Board certified valve is rated for a maximum service temperature of 250°F, ensuring reliable performance in demanding commercial and industrial heating applications.

• High BTU Rating: Offers a 1,641,000 BTU capacity to protect high-output boiler systems.
• Oversized Discharge: The 1" expanded outlet allows for rapid pressure relief and prevents backpressure during discharge.
• Corrosion Resistant Construction: Built with a heavy-duty bronze body and a diaphragm-isolated spring chamber for maximum durability.
• ASME Certified: Fully compliant with ASME Section IV standards for heating boilers (HV rating).
• Positive Shut-off: High-quality silicone seating ensures a tight seal and reduces maintenance cycles.

What is the maximum temperature rating for the Conbraco 10-614-12?
This valve is rated for a maximum operating temperature of 250°F (121°C), suitable for most high-capacity hot water heating systems.

Can this relief valve be used for steam applications?
No, the 10-600 series is specifically a water relief valve designed for hot water boilers and supply systems; it is not rated for steam service.

How does the diaphragm protect the valve?
The fabric-reinforced diaphragm isolates the spring and the guide area from the water, which prevents corrosion and mineral deposits from affecting the valve's set point.
