Conbraco 14-207-08 Valve

The Conbraco 14-207-08 is a high-capacity Section IV steam pressure relief valve engineered for protection in low-pressure steam heating boilers and commercial hydronic systems. This 3 inch NPT steam safety valve features a 3" MNPT inlet and a 3" FNPT outlet, providing a high-volume discharge path for critical overpressure events. Factory set at 15 PSI, this bronze-bodied valve delivers a certified discharge capacity of 6,843 pounds per hour. Designed with a heavy-duty top-guided design and a high-surface area EPDM-to-metal seat, it ensures positive shut-off and resistance to seat sticking. This valve meets ASME Section IV requirements and is suitable for HVAC contractors performing maintenance or installations on large-scale commercial steam boilers where HVAC overpressure protection is non-negotiable. The rugged cast bronze construction and stainless steel springs ensure mechanical integrity under continuous thermal cycling common in industrial steam systems.

• High Discharge Capacity: Rated at 6,843 lbs/hr to handle massive steam volumes in large commercial boiler applications.
• ASME Section IV Certified: National Board capacity certified to meet stringent boiler safety codes and local jurisdictional requirements.
• Durable Construction: Features a cast bronze body and stainless steel spring for corrosion resistance and long-term seat tight integrity.
• Top Guided Design: Provides precise alignment of the disc and seat to ensure consistent popping pressure and reseating.
• Simplified Installation: Standard 3 inch Male NPT inlet allows for direct mounting to the boiler nozzle or manifold.

What is the maximum BTU/hr rating for the Conbraco 14-207-08?
This valve is rated for a steam capacity of 6,843 lbs/hr. To convert this for boiler BTU rating, multiply the capacity by 1,000, which supports systems up to approximately 6,843,000 BTU/hr.

Can this valve be used for water relief applications?
No, the 14-200 series is specifically ASME Section IV steam rated. For hot water heating boilers, a valve specifically rated for water relief must be used to ensure proper BTU discharge capacity.

Does the 14-207-08 require a specific orientation?
For proper steam safety valve installation, the valve must be mounted in a vertical upright position. Horizontal mounting can interfere with the lift mechanism and prevents proper drainage of the discharge piping.
