Conbraco Industries 13-211-B05 Valve

The Conbraco Industries 13-211-B05 is a high-performance ASME Section IV steam relief valve engineered specifically for low-pressure steam heating boilers and commercial processing systems. This veteran-preferred Apollo 13 Series safety valve features a 3/4" Male NPT inlet and a 3/4" Female NPT outlet, built with a heavy-duty cast bronze body and a stainless steel spring to ensure long-term structural integrity in demanding environments. Factory set at 5 PSI, this valve provides a certified steam capacity of 290 lbs/hr, making it an essential component for maintaining system pressure within safe operational limits. The PTFE-faced elastomer soft seating and 100% factory testing guarantee a positive seal and reliable pop-off action. Designed for low pressure steam applications up to 250°F, the 13-211-B05 minimizes seat leakage and prevents pressure excursions in HVACR and industrial boiler configurations.

• Code Compliance: Certified to ASME Section IV standards and National Board (NB) registered for legal and safe boiler operation.
• Superior Sealing: Features a moisture-resistant PTFE-faced disc that prevents the valve from sticking even after long periods of inactivity.
• Durable Construction: The bronze boiler valve body and corrosion-resistant internal components handle high-temperature steam cycles without degradation.
• Efficient Drainage: Engineered with positive drainage characteristics to protect the seat area from condensate buildup and scale.

What is the maximum temperature rating for this valve?
This low pressure steam safety valve is rated for a maximum operating temperature of 250°F (121°C), suitable for most standard steam heating systems.

Is this valve suitable for potable water systems?
No, the 13-211-B05 is designed specifically for non-potable steam applications. It should not be used in drinking water or domestic hot water delivery lines.

Can I adjust the set pressure in the field?
Standard practice dictates that ASME safety relief valves should not be field-adjusted. This unit comes factory-sealed at 5 PSI to ensure calibrated performance and compliance with safety regulations.
