Conbraco 13-211-B10 Valve

The Conbraco 13-211-B10 is a high-capacity bronze safety relief valve specifically engineered for low pressure steam heating boilers and industrial systems. Designed to meet strict ASME Section IV code requirements, this valve features a 3/4" Male NPT inlet and a 3/4" Female NPT outlet, ensuring high-flow performance in critical steam applications. With a factory-fixed setting of 10 PSI, it provides a certified discharge capacity of 383 pounds per hour (PPH), effectively preventing over-pressurization in residential and commercial boilers. Constructed with a heavy-duty ASTM B584 bronze body and a PTFE-faced disc, the 13-211-B10 ensures a positive seal and superior corrosion resistance even in high-temperature environments up to 250°F. The inclusion of a stainless steel spring and a professional-grade lift lever allows for manual testing and reliable seat drainage, making it a standard choice for contractors focused on durability and HVAC system safety.

• High-Flow Steam Discharge: Rated at 383 PPH to handle significant thermal loads in Section IV steam systems.
• Durable Bronze Construction: Built with an ASTM B584 bronze body and brass trim for long-term survival in harsh hydronic environments.
• Leak-Proof Sealing: Features a PTFE-faced disc that resists sticking and ensures a tight shut-off after discharge.
• ASME National Board Certified: Fully compliant with safety standards for low-pressure steam heating and supply boilers.
• Self-Draining Design: Engineered to provide positive drainage of condensate away from the seat area to prevent mineral buildup and corrosion.

What is the difference between an ASME Section IV and Section VIII valve?
The Conbraco 13-211-B10 is an ASME Section IV valve, meaning it is specifically tested and certified for low-pressure steam heating boilers (operating up to 15 PSI), whereas Section VIII valves are intended for high-pressure unfired pressure vessels.

Can this valve be used for air or water service?
While some Series 13 valves offer air service options, the 13-211-B10 is primarily a steam pressure relief valve. For water or air applications, always verify that the specific model carries the proper "NB" and "UV" or "HV" stamps for that medium.

How do I ensure the valve is installed correctly?
For optimal performance, the valve must be installed in a vertical position with the discharge piping directed away from personnel. Ensure the 3/4" MNPT inlet is securely threaded into the boiler's dedicated relief port without restricting the flow path.
