Conbraco 10-615-10 Valve

As a seasoned contractor, you know that protecting a high-output hydronic system requires more than just a standard relief valve; it requires the high-capacity performance of the Conbraco 10-615-10. This hot water boiler safety relief valve is specifically engineered for ASME Section IV applications, providing a massive 2,295,000 BTU/hr relief capacity. The 1" FNPT inlet and 1.25" FNPT expanded outlet design are critical for reducing backpressure and ensuring rapid discharge during overpressure events. Built with a rugged bronze body safety valve construction (ASTM B584), it features a silicone seat for tight shut-off and a fabric-reinforced diaphragm that isolates the spring from the water, preventing corrosion and mineral buildup. Factory-set at 50 PSI, the Apollo 10-615-10 is the industry standard for reliable pressure regulation in commercial and large-scale residential heating systems where ASME Section IV certified components are non-negotiable for code compliance and system integrity.

• High BTU Rating: Offers a 2,295,000 BTU/hr capacity, ideal for high-demand heating boilers.
• Expanded Outlet: Features a 1.25" outlet to maximize flow and minimize discharge piping restrictions.
• Corrosion Resistance: Utilizing a bronze body and plated alloy steel spring for long-term durability in harsh environments.
• Diaphragm Isolation: The internal spring chamber is completely isolated from the process media to prevent scaling.
• Code Compliant: National Board capacity certified and meets ASME Section IV requirements.

• What is the maximum temperature rating for this valve? This unit is rated for service temperatures up to 250°F.
• Can this be mounted horizontally? No, for proper operation and drainage of the seat area, this valve must be installed with the spindle in the vertical upright position.
• Is the outlet size the same as the inlet? No, this model features an oversized 1.25" outlet to handle the high-volume steam/water discharge typical of a 1" 50 PSI set point.
