Conbraco 13-211-B08 Valve

The Conbraco 13-211-B08 is a heavy-duty, low pressure steam safety relief valve engineered specifically for technical compliance with ASME Section IV heating systems. Designed for low pressure steam heating boilers, this valve is factory-set at 8 PSI to provide critical overpressure protection for commercial and industrial applications. Built with a rugged bronze body (ASTM B584) and a corrosion-resistant stainless steel spring, it ensures high-capacity performance and long-term reliability in demanding environments. Implementation of a 3/4" Male NPT inlet and a 3/4" Female NPT outlet allows for a standard angle configuration, while the PTFE-faced disc provides a positive, elastomeric seal that prevents simmering and leakage. This National Board certified valve features a discharge capacity of approximately 475 lbs/hr (at 15 psi reference), ensuring sufficient venting for medium-scale boiler sets. For contractors, the top-guided design and raised seating area are essential for technical durability and consistent steam pressure regulation.

• ASME Section IV Certified: Specifically calibrated for low-pressure steam boiler safety compliance.
• Robust Bronze Construction: Features a high-quality bronze safety valve body to withstand high-temperature saturated steam.
• High Venting Capacity: Engineered for efficient thermal discharge to prevent system-wide overpressurization.
• Positive Seal Design: Utilizes a PTFE-faced disc for superior shut-off and resistance to seat sticking.
• Standard NPT Connections: Simplifies installation with 3/4 inch NPT male-to-female threading.

Common Questions

This valve is rated for saturated steam service up to 250°F, making it ideal for low-pressure hydronic and steam heating systems.

The 13-211-B08 is primarily designed and ASME Section IV certified for steam applications. For liquid or air service, ensure the valve meets the specific code requirements of your local jurisdiction.

No, this valve is factory-set and sealed at 8 PSI. Tampering with the factory seal will void the safety certification and may compromise the integrity of the boiler system.
