Conbraco 10-615-09 Valve

The Conbraco 10-615-09 is a high-capacity ASME Section IV certified safety relief valve engineered for the protection of hot water heating boilers and hydronic systems. This Apollo RVW61 series valve features a 1-inch FNPT inlet and an expanded 1.25-inch FNPT outlet, specifically designed to handle a discharge capacity of 2,114,000 BTU/hr at a factory-set pressure of 45 PSI. The bronze body construction (ASTM B584) ensures long-term corrosion resistance in demanding mechanical room environments. A key technical feature is the diaphragm isolated spring chamber, which utilizes a fabric-reinforced molded diaphragm to prevent water from contacting the high-tensile alloy steel spring, significantly reducing the risk of scale buildup or spring fatigue. With a maximum temperature rating of 250°F, this valve provides reliable overpressure protection for large-scale residential and commercial heating equipment. National Board capacity certification ensures this safety relief valve meets strict code requirements for pressure vessel safety.

• High BTU Capacity: Rated for 2,114,000 BTU/hr to support high-output boiler systems.
• Corrosion-Resistant Construction: Durable bronze unibody and brass trim withstand harsh hydronic conditions.
• Isolated Spring Design: EPDM/Silicone diaphragm keeps the spring chamber dry, ensuring consistent set-pressure performance.
• Oversized Outlet: 1.25-inch expanded discharge port reduces backpressure during full-flow relief events.
• Enhanced Sealing: Features a silicone seat for tight shut-off and resistance to seat sticking.

What is the maximum operating temperature for the 10-615-09?
This valve is rated for a maximum temperature of 250°F (121°C), making it suitable for most standard and high-temperature hot water heating applications.

Does this valve require specific mounting orientation?
Yes, for proper operation and to satisfy ASME code, the valve must be mounted in a vertical upright position directly to the boiler tapping or a clean pipe connection without intervening valves.

What is the difference between the 10-605 and 10-615?
While both are 1-inch inlet valves, the 10-615 features an expanded 1.25-inch outlet for higher discharge capacity compared to the standard 1-inch outlet on the 10-605 model.
