Conbraco 10-615-05 Valve

The Conbraco 10-615-05 is an ASME Section IV certified high-capacity relief valve designed specifically for the protection of hot water heating boilers and hydronic systems. This RVW61 model features a 1" Female NPT inlet and an expanded 1 1/4" Female NPT outlet, allowing for superior discharge rates in over-pressure scenarios. Factory set at 30 PSI, it provides a massive 1,570,000 BTU capacity, ensuring safety in large-scale residential and commercial heating applications. Built with a heavy-duty bronze body (ASTM B584) and a silicone seat, this valve is engineered for durability at temperatures up to 250°F. The internal design utilizes a fabric-reinforced molded diaphragm that effectively isolates the alloy steel spring from the process media, preventing corrosion and spring fatigue. This hot water pressure relief valve is the reliable choice for technicians requiring a National Board capacity-certified safety device that handles high thermal inputs without compromising system integrity.

• Extreme BTU Rating: Certified for 1,570,000 BTU/hr to protect high-output boiler systems.
• Advanced Diaphragm Design: Features an isolated spring chamber to prevent mineral buildup and corrosion on the plated steel spring.
• Corrosion-Resistant Construction: Rugged bronze body and spring cage provide long-term reliability in demanding hydronic environments.
• Oversized Discharge: The 1 1/4" expanded outlet reduces backpressure and facilitates maximum flow during relief cycles.
• Certified Safety: National Board capacity certified and registered in all Canadian provinces (CRN #0G8547.5C).

What is the maximum operating temperature for this valve?
The 10-615-05 is rated for hot water service up to 250°F (121°C).

Can this relief valve be used for steam applications?
