Conbraco 13-214-B15 Valve

The Conbraco 13-214-B15 (also labeled as the Apollo RVS13-112) is a high-capacity low pressure steam safety valve designed specifically for ASME Section IV heating boilers and systems. Built with a heavy-duty bronze body and a stainless steel spring, this valve is engineered to withstand the rigors of commercial steam environments. It features a 1-1/2" Male NPT inlet and a 2" Female NPT outlet, factory-set at 15 PSI with a discharge capacity of 1,900 pounds per hour. The integration of a PTFE-faced disc (or EPDM in certain configurations) ensures a positive seal and helps prevent seat leakage, while the nozzle-type design provides high-volume relief when pressure thresholds are exceeded. For contractors managing steam heating plants, this National Board certified valve offers the reliability required for 250°F maximum temperature service in non-potable applications.

• High Steam Capacity: Rated for 1,900 lb/hr to handle significant blowdown requirements in ASME Section IV systems.
• Durable Construction: Features a corrosion-resistant bronze finish and internal brass trim for longevity in harsh hydronic environments.
• Optimized Sealing: Equipped with a TFE/PTFE seat to minimize simmer and improve shut-off reliability after a high-pressure event.
• Standard Compliance: Fully National Board certified and registered in all Canadian provinces (CRN 0G8547.5C).
• Installation Versatility: The 1-1/2" MNPT x 2" FNPT angle configuration facilitates efficient piping layout and condensate drainage.

What is the maximum temperature rating for this valve?
The Conbraco 13-214-B15 is rated for saturated steam service up to a maximum temperature of 250°F (121°C).

Can this valve be used for water pressure relief?
No, this specific model is a Section IV steam pressure relief valve calibrated for steam heating boilers. Using it for liquid service may lead to improper discharge and equipment damage.

Is this valve lead-free?
No, it is designed for non-potable steam heating applications and does not comply with the Safe Drinking Water Act for human consumption systems.
