Conbraco 10-604-25 Valve
The Conbraco 10-604-25 is a high-capacity hot water boiler safety relief valve engineered for aggressive pressure protection in commercial and industrial hydronic systems. This Apollo 10-600 series valve features a 3/4" Female NPT inlet and outlet, factory-set at 125 PSI to ensure system integrity during thermal expansion or control failure. With an ASME Section IV certified capacity of 2,639,000 BTU/hr, it is specifically designed to handle the high discharge requirements of large-scale heating equipment. The bronze body construction and silicone seat provide superior corrosion resistance and a tight seal up to 250°F. A fabric-reinforced molded diaphragm isolates the stainless steel spring from the water media at all times, preventing scale buildup and ensuring consistent pop-off performance. For contractors and HVAC technicians, this ASME safety relief valve offers a reliable, low-maintenance solution for hot water heating boilers where high-capacity pressure relief is non-negotiable.
Key Benefits:- High BTU Capacity: National Board certified for 2,639,000 BTU/hr to protect large hydronic systems.
- Durable Construction: Heavy-duty bronze body and spring cage stand up to harsh mechanical room environments.
- Contamination Protection: Isolated spring chamber prevents media contact with the spring, extending component life.
- Precision Sealing: High-temperature silicone seat ensures a positive shut-off after every lift cycle.
- Compliance Ready: ASME Section IV and CRN registered for strict jurisdictional requirements.
- What is the maximum operating temperature for the 10-604-25? This valve is rated for a maximum service temperature of 250°F (121°C).
- Can this relief valve be mounted horizontally? No, for proper safety and drainage, the valve must be mounted in a vertical, upright position directly to the boiler.
- Is this valve suitable for steam service? No, the 10-600 series is specifically for hot water heating boilers and supply systems; it is not intended for steam applications.
