Conbraco 12-206-08 Valve

The Conbraco 12-206-08 is a high-capacity, ASME Section IV steam pressure relief valve engineered for the overpressure protection of low-pressure steam heating boilers. Built with a professional-grade cast bronze body and a full nozzle design, this 15 PSI steam safety valve is optimized for medium-to-large commercial systems requiring a 3,529 PPH steam capacity. This unit features a 2-1/2" Male NPT inlet and a 2-1/2" Female NPT outlet, ensuring a secure and standardized fit for heavy-duty boiler headers. The internal mechanism utilizes a PTFE-faced elastomer soft seat for positive shut-off and resistance to seat sticking, even during extended idle periods. A rust-proof steel spring and top-guided disc assembly provide consistent set-pressure reliability, while the 3/8" NPT side tapping facilitates necessary drain piping to prevent condensate accumulation around the seat area.

• High Relieving Capacity: National Board certified to handle 3,529 pounds per hour, meeting strict ASME Section IV requirements for steam service.
• Durable Construction: Features a corrosion-resistant bronze body and a chrome-plated brass disc for longevity in high-moisture environments.
• Superior Sealing: The TFE-coated EPDM seat provides an airtight seal that prevents simmering and premature leakage at 15 PSIG.
• Field Ready: Equipped with a 3/8" NPT side drain to assist in managing condensate and a rugged lever handle for manual lift testing.
• Regulatory Compliance: Registered in all Canadian provinces (CRN 0G8547.5C) and "HV" National Board certified.

What is the maximum temperature rating for this valve?
This Apollo 12-206-08 is rated for saturated steam service up to 250°F (121°C).

Can this be used for hot water heating applications?
No, this specific model is a "pop-action" safety valve designed specifically for low pressure steam boilers. For water service, a safety relief valve with continuous expansion capabilities is required.

How should the discharge piping be configured for this 2-1/2" valve?
Technicians must ensure the discharge piping is no smaller than the 2-1/2" FNPT outlet. It should be independently supported and pitched to the 3/8" drain to prevent backpressure or condensate load on the valve internals.
