Conbraco 14-206-08G Valve

Professional-grade Conbraco 14-206-08G (Apollo) 2-1/2" steam pressure relief valve, engineered specifically for high-capacity overpressure protection in ASME Section IV low-pressure heating boilers. This high-volume safety valve features all-bronze construction with an ASTM B584 grade body and a corrosion-resistant rust-proof steel spring, ensuring peak reliability in demanding commercial and industrial environments. The 15 PSI set pressure supports a certified steam discharge capacity of 4,676 lbs/hr, providing critical protection for medium to large-scale boiler systems. This model includes a standard test gag option for hydrostatic testing, alongside a PTFE-faced EPDM O-ring for a positive seat seal that prevents simmering. With its 2-1/2" Male NPT inlet and 2-1/2" Female NPT outlet, this 14 series valve delivers a secure, leak-free connection for veteran contractors requiring National Board capacity-certified safety components that meet stringent HVACR technical standards. The unit also includes a 3/8" NPT side tapping for efficient condensate drainage.

• ASME Section IV Certified: Specifically rated for low-pressure steam heating boiler safety with National Board capacity listing.
• High Discharge Capacity: Manages up to 4,676 pounds per hour to prevent catastrophic failure in 15 PSI systems.
• Durable Bronze Body: Heavy-duty ASTM B584 bronze construction resists corrosion and thermal stress.
• Hydrostatic Test Gag: Built-in gag prevents the valve from lifting during initial system pressure testing and commissioning.
• Positive Seal Design: Utilizes a PTFE-coated disc and EPDM O-ring for tight shutoff and extended service life.

What is the purpose of the test gag on the 14-206-08G?

The test gag is used during hydrostatic testing of the boiler to temporarily prevent the valve from opening at its 15 PSI set point, allowing the contractor to test the vessel at higher pressures without removing the valve.

Can this steam relief valve be installed horizontally?

No. For proper operation and drainage of condensate away from the seat area, this valve must be mounted in a vertical, upright position directly to the boiler tapping.

What is the maximum operating temperature for this unit?

The Conbraco 14-206-08G is designed for saturated steam applications with a maximum temperature service of 250°F.
