Conbraco 13-211-B15 Valve

The Conbraco 13-211-B15 is a high-capacity ASME Section IV steam pressure relief valve designed specifically for low-pressure steam heating boilers and commercial processing equipment. Featuring a durable bronze body and a 3/4" Male NPT inlet by 3/4" Female NPT outlet, this valve is factory set at 15 PSI to ensure precise overpressure protection. With a discharge capacity of 475 lbs/hr, it effectively manages saturated steam service up to 250°F. The 13 series utilizes a PTFE-faced disc and a stainless steel spring to maintain a positive seal and resist seat sticking, even in harsh environments. As a National Board certified safety device, it provides critical boiler overpressure protection for legacy and modern steam systems. Contractors rely on its corrosion-resistant construction and top-guided stem for consistent pop-action performance, making it a standard replacement for maintaining system integrity in industrial and residential steam applications.

• ASME Section IV Certified: Purpose-built and safety-rated for low-pressure steam heating systems.
• High Discharge Capacity: Rated for 475 pounds per hour (PPH) to quickly evacuate excess pressure.
• Reliable Sealing: Features a non-stick TFE disc-to-metal seat that prevents bonding and ensures a tight shut-off.
• Rugged Construction: Cast bronze body (ASTM B584) and stainless steel springs provide superior longevity against corrosion.
• Standardized Fit: 3/4" NPT threads allow for easy integration into existing steam boiler piping.

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

Can this be used for water or air applications?
No, the Conbraco 13-211-B15 is specifically engineered and certified for low-pressure steam service only.

Is the discharge capacity sufficient for my boiler?
You must verify that the 475 lbs/hr capacity exceeds the steam generation rate of your boiler to comply with safety codes.
