Conbraco 10-606-05 Valve

The Conbraco 10-606-05 is a high-capacity hot water pressure relief valve engineered specifically for protection against over-pressurization in large-scale commercial and industrial boiler systems. Featuring a 1-1/4" NPT female inlet and 1-1/4" NPT female outlet, this valve is factory set at a 30 PSI relief pressure. With a discharge capacity of 2,316,000 BTU/hr, it meets the rigorous demands of high-output hydronic heating equipment. The 10-600 series utilizes a heavy-duty bronze body and a silicone seat to ensure positive shut-off and resistance to thermal bonding. This ASME Section IV certified safety valve is a standard replacement for Apollo and Conbraco systems requiring high-flow discharge. For contractors managing large btu boiler installs, the heavy-duty bronze construction provides the durability needed for high-temperature service. Ensure the discharge piping matches the 1-1/4 inch orifice size to prevent backpressure issues and maintain the rated BTU relief capacity during a high-pressure event.

Key Benefits:

• High Discharge Capacity: Rated at 2,316,000 BTU/hr, making it suitable for high-output commercial boilers.
• Corrosion Resistance: Built with a rugged bronze body and stainless steel springs for long-term reliability in hydronic environments.
• ASME Section IV Certified: National Board certified to meet stringent safety codes for hot water heating boilers.
• Positive Seal: Features a silicone seat for a tight seal and enhanced resistance to high temperatures and chemicals.
• Standardized Fit: 1-1/4" FNPT connections allow for direct integration into existing manifold or boiler trim configurations.

Common Questions:

Can this valve be used for steam applications?
No, the 10-606-05 is specifically designed for hot water relief valve applications and is rated under ASME Section IV for water heating boilers only.

What causes a relief valve to drip after reaching its set pressure?
Dripping usually indicates that scale or debris is trapped on the seat. While the silicone seat is durable, it is recommended to manually lift the test lever periodically to flush out sediment that could compromise the seal.

Does this valve come with a factory set pressure?
Yes, this model is factory-set and sealed at 30 PSI. Field adjustments should not be attempted as they can void the ASME certification and compromise system safety.
