Conbraco 10-616-20 Valve

The Conbraco 10-616-20 is a heavy-duty high capacity pressure relief valve engineered specifically for high-output hot water heating boilers and large-scale hydronic systems. This 10 series relief valve features a 1-1/4" FNPT inlet and a 1-1/2" FNPT outlet, providing the necessary flow area to prevent over-pressurization in commercial installations. Factory set at 100 PSI, this valve is rated for a massive 7,101,000 BTU/hr capacity, ensuring it meets strict ASME Section IV safety requirements. The bronze body construction and EPDM O-ring provide superior temperature resistance and a reliable seal against high-head pressure. Designed for technicians who need a high-performance boiler safety valve, the 10-616-20 integrates a stainless steel spring and a non-sticking Teflon-faced silicone seat to ensure positive shut-off after emergency activation. Reliable and robust, it is the standard for protecting large-scale boiler systems from catastrophic pressure spikes.

• Industry-Leading Capacity: certified for 7,101,000 BTU/hr to handle high-demand commercial boilers.
• Durable Construction: Features a corrosion-resistant bronze body and stainless steel internal components for long-term reliability.
• High-Temperature Rating: Engineered to withstand the thermal stresses of modern hydronic heating environments.
• Precise Calibration: Factory set and sealed at 100 PSI to maintain system integrity and safety compliance.
• Large Porting: The 1-1/4" x 1-1/2" configuration reduces backpressure during discharge and optimizes flow rates.

What is the maximum temperature rating for the Conbraco 10-616-20?
This valve is designed for hot water service and is typically rated for temperatures up to 250°F, aligning with ASME Section IV boiler requirements.

Can this relief valve be used for steam applications?
No, the 10-616 series is specifically designed for hot water heating systems. For steam service, an ASME Section I or Section VIII rated safety valve must be used.

In what orientation should this valve be installed?
To ensure proper performance and drainage of the discharge line, the valve must be installed in a vertical position with the spindle upright.
