Conbraco 10-614-20 Valve

Install the Conbraco 10-614-20 high-capacity pressure relief valve to ensure reliable overpressure protection for hot water heating systems. This ASME Section IV certified safety valve is a staple for veteran technicians managing large-scale boilers and commercial hydronic systems. Factory set at 100 PSI, it supports a massive thermal discharge capacity of 2,536,000 BTU/hr. The 3/4" female NPT inlet is paired with an oversized 1" female NPT outlet to allow for maximum flow and rapid pressure reduction during a critical event.

The Apollo 10-614-20 is engineered for durability in high-demand environments. It features a rugged bronze body (ASTM B584) and an alloy steel plated spring housed in a diaphragm-isolated chamber. This design keeps the spring free from water exposure, preventing scale buildup and potential sticking. The silicone seat provides a tight seal at operating pressures, while the elevated seat design facilitates drainage away from the sealing surface. This valve is a direct replacement for contractors needing a National Board certified safety device capable of handling temperatures up to 250°F.

• High BTU Rating: Optimized for high-output boilers with a 2,536,000 BTU capacity for superior safety coverage.
• Oversized Outlet: The 1" FNPT discharge port reduces backpressure and ensures faster relief during activation.
• Diaphragm-Isolated Spring: Specifically designed to isolate internal components from the media, extending the service life of the 100 PSI set point.
• ASME Section IV Certified: Fully compliant with safety standards for hot water heating boilers and supply systems.

• Can this be used for steam applications? No, this safety relief valve is specifically designed and certified for hot water heating systems only.
• What is the maximum operating temperature? This valve is rated for a maximum temperature of 250°F.
• Does it require a specific mounting orientation? Yes, for proper operation and drainage, the valve must be installed in a vertical, upright position.
