Conbraco 10-605-05 Relief Valve

The Conbraco 10-605-05 Relief Valve is a high-capacity solution engineered for hot water heating boilers and large-scale hydronic systems. This ASME Section IV certified safety valve features a robust bronze body construction and is factory-set at 30 PSI, providing a substantial 1,339,000 BTU/hr discharge capacity. Designed with a 1" female NPT inlet and a 1" female NPT outlet, this 10-600 series valve utilizes a diaphragm-isolated spring chamber to protect internal components from water sediment and corrosion. The silicone seat ensures a tight seal and reliable pop-action during overpressure events, while the stainless steel spring maintains consistent tension across its 250°F maximum temperature range. For mechanical contractors, the Apollo 10-605-05 represents a reliable standard in boiler pressure protection, offering an elevated seat design that facilitates superior drainage and prevents liquid accumulation around the sealing surface.

• ASME Section IV Certified: National Board capacity certified for high-output commercial and residential heating systems.
• Corrosion-Resistant Internals: Features a bronze alloy body and stainless steel spring for longevity in demanding environments.
• High BTU Rating: Rated for 1,339,000 BTU/hr to handle significant thermal expansion and pressure spikes.
• Isolated Spring Chamber: Diaphragm design prevents media from reaching the spring, reducing the risk of mineral buildup and sticking.
• Standard FNPT Connections: 1" x 1" FNPT configuration allows for straightforward integration into existing piping headers.

What is the maximum operating temperature for this valve?
This 10-600 series valve is rated for a maximum temperature of 250°F.

Can this relief valve be mounted horizontally?
No, for proper operation and to satisfy ASME code, the valve must be installed in a vertical, upright position directly on the boiler or pressure vessel.

Does this model include a test lever?
Yes, it is equipped with a standard steel lift lever for manual testing of the seating surface and disc movement.
