Conbraco 10-617-07 Valve

The Conbraco 10-617-07 is a high capacity pressure relief valve engineered for heavy-duty commercial boiler systems and large-scale hydronic heating applications. Featuring a 1-1/2" Female NPT inlet and a 2" Female NPT outlet, this ASME Section IV certified valve is factory set at 40 PSI. With a massive thermal discharge rating of 4,548,000 BTU/hr, it provides critical overpressure protection for high-output hot water heating boilers. The construction utilizes high-quality bronze for the body and internal components to resist corrosion and scaling in demanding environments. This boiler safety valve is designed for high-flow discharge, ensuring rapid pressure stabilization to maintain vessel integrity. Technicians should verify that the BTU capacity of the valve exceeds the gross output of the heating system to ensure compliance with local mechanical codes and HVAC safety standards. This 10-600 series model is the industry standard for ASME pressure relief when reliability and high volume capacity are non-negotiable.

Key Benefits

• High BTU Rating: Provides an impressive 4,548,000 BTU/hr capacity, suitable for large commercial boiler plants.
• Superior Flow Path: The enlarged 2-inch outlet reduces backpressure during discharge, ensuring maximum flow rates.
• Durable Construction: Built with robust bronze materials to withstand the thermal cycling typical of intensive hydronic systems.
• ASME Certified: National Board certified to meet Section IV requirements for hot water heating boilers.
• Exact Pressure Relief: Factory set and sealed at 40 PSI for precise performance and tampering prevention.

Common Questions

Is the Conbraco 10-617-07 suitable for steam applications?
No, this specific model is designed and rated strictly for hot water heating boilers and liquid service. For steam applications, an ASME Section I or VIII rated valve must be selected based on the specific media requirements.

How do I determine if 40 PSI is the correct setting for my system?
The relief valve setting should be based on the Maximum Allowable Working Pressure (MAWP) of the boiler. Typically, the valve is set at or below the MAWP to ensure the safety of the pressure vessel.

What causes a relief valve to weep or drip after installation?
Weeping is often caused by thermal expansion in a closed system without an expansion tank, or by debris trapped on the valve seat. It is critical to flush the system thoroughly before putting the valve into service.
