Conbraco 10-606-25 Valve

The Conbraco 10-606-25 is a high-capacity ASME Section IV certified safety relief valve designed specifically for the protection of hot water heating boilers and supply systems. This 1-1/4 inch FNPT valve features a rugged bronze body (ASTM B584) and a silicone seat to ensure positive shut-off and resistance to seat sticking. With a factory set pressure of 125 PSI and a massive steam relieving capacity of 7,390,000 BTU/hr, it provides critical overpressure protection by exhausting excess energy if primary controls fail. The 10-600 series utilizing a diaphragm-isolated spring chamber prevents corrosive system fluids from making contact with the alloy steel spring, maintaining consistent set-point reliability in demanding hydronic environments. Ideal for commercial boiler applications, this technical-grade component is National Board capacity certified and CRN registered, ensuring compliance with rigorous safety codes and standard piping requirements.

• High BTU Capacity: Rated at 7,390,000 BTU/hr to handle large-scale commercial hot water systems.
• Corrosion Resistance: Features an ASTM B584 bronze body and stainless steel or plated alloy internals for longevity.
• Isolated Spring Design: The fabric-reinforced diaphragm keeps the spring chamber dry, preventing mineral buildup and spring fatigue.
• Precise Overpressure Protection: Designed to achieve 90% of actual capacity at only 10% overpressure per ASME HV standards.
• Serviceable Design: Equipped with a standard lift lever for required periodic manual testing by maintenance personnel.

What is the maximum operating temperature for the 10-606-25?
This valve is rated for a maximum service temperature of 250°F (121°C).

Can I install this valve horizontally?
No, for proper operation and to satisfy most local codes, the valve must be mounted in a vertical upright position directly to a clean opening on the top of the pressure vessel.

What size discharge piping should be used?
The discharge piping must be at least 1-1/4" NPT and should not be smaller than the valve outlet to avoid backpressure that could reduce relieving capacity.
