Conbraco 10-618-12 Valve
The Conbraco 10-618-12 Valve is a high capacity pressure relief valve specifically engineered for ASME Section IV hot water heating boilers and large-scale hydronic systems. This industrial-grade safety relief valve is factory set at 60 PSI and features a massive 10,305,000 BTU capacity, making it the standard choice for protecting heavy-duty commercial equipment from overpressurization. Built with a rugged ASTM B584 bronze body and a corrosion-resistant alloy steel spring, the 10-600 series utilizes a fabric-reinforced diaphragm designed to isolate the spring from water contact, significantly reducing the risk of mineral buildup or mechanical failure. The 2" Female NPT inlet and 2-1/2" Female NPT expanded outlet permit high-volume discharge to safely vent excess system pressure. This National Board certified relief valve supports operating temperatures up to 250°F and is essential for contractors maintaining system integrity in high-demand boiler rooms and supply systems.
Key Benefits
- Maximum Discharge Performance: Features an oversized 2-1/2" outlet to eliminate backpressure and ensure the full 10,305,000 BTU/HR rating is achieved during emergency relief.
- Internal Component Protection: The diaphragm-isolated spring chamber prevents sediment and corrosive water from reaching critical internal parts, extending service life in harsh environments.
- Certified Safety Standards: Fully ASME Section IV certified and National Board capacity rated to meet strict commercial building codes and safety regulations.
- Durable Construction: High-performance silicone seating provides a resilient seal and prevents the disc from sticking even after long periods of inactivity.
Common Questions
What is the purpose of the expanded outlet on the 10-618-12?
The expanded 2-1/2" outlet allows for lower discharge velocity and ensures the valve can vent its full rated BTU capacity without the restriction of backpressure, which is critical for large commercial hot water boilers.
Can this valve be used for steam applications?
No, the Conbraco 10-618-12 is an ASME Section IV HV rated valve specifically designed for hot water heating systems. For steam service, an ASME Section I or VIII safety valve must be selected based on the specific system requirements.
Where should this relief valve be installed in the system?
For optimal safety, it should be installed directly into the top of the boiler or on the supply piping immediately adjacent to the heat source, with the spindle in a vertical position and no shut-off valves between the boiler and the relief valve.
