Conbraco 10-618-25 Valve
The Conbraco 10-618-25 Valve is a high capacity pressure relief valve engineered for the rigorous demands of commercial hot water heating boilers and large-scale hydronic heating systems. As an ASME Section IV certified safety device, it provides critical overpressure protection with a substantial 19,435,000 BTU capacity. This 2 inch NPT inlet by 2-1/2 inch NPT outlet valve features a bronze body and an elevated seat design, which ensures positive drainage of water away from the seating area to prevent mineral buildup and seat sticking. The silicone seat and alloy steel spring are designed for high-temperature stability, with a maximum operating temperature of 250°F. Factory set at 125 PSI, this Apollo safety relief valve is the industry standard for boiler pressure relief in high-output applications. Its corrosion resistant construction and diaphragm isolated spring chamber protect internal components from the system media, ensuring consistent HVAC safety valve performance and reliability for mechanical contractors and facility engineers.
Key Benefits- Extreme Discharge Capacity: Rated at over 19 million BTU/hr, making it suitable for high-output industrial and commercial boilers.
- ASME Section IV Certified: Meets National Board capacity certification standards for institutional and commercial heating safety.
- Durable Bronze Construction: Built with an ASTM B584 bronze body and silicone seat for corrosion resistance and leak-free operation.
- Debris Protection: The elevated seat design facilitates effective drainage, reducing the risk of seat fouling from system sediment.
- Isolated Spring Chamber: A reinforced diaphragm keeps the alloy steel spring separate from the water flow to prevent scale and corrosion.
What is the primary application for the Conbraco 10-618-25?
This valve is specifically designed as a safety relief valve for hot water boilers in high-capacity heating systems, protecting against excessive pressure caused by control failure.
Can this valve be used for steam service?
No, the 10-618 series is intended for hot water heating and supply systems; steam applications require an ASME Section I or Section VIII rated valve.
What are the connection sizes for this model?
It features a 2" Female NPT inlet and an expanded 2-1/2" Female NPT outlet to facilitate high-volume discharge during a relief event.
