Conbraco Industries 13-101-B15 Valve

The Conbraco Industries 13-101-B15 is a high-performance 3/4" Male NPT safety valve engineered specifically for low-pressure steam heating boilers and equipment. This Section IV Steam Pressure Relief Valve is factory set at 15 PSI, providing a rated discharge capacity of 410 pounds per hour. Constructed with a heavy-duty bronze body and a corrosion-resistant stainless steel spring, it ensures reliable overpressure protection in demanding commercial and industrial environments. The top outlet discharge design facilitates efficient venting while the PTFE-faced disc provides a positive, bubble-tight seal to prevent simmering. As a National Board certified component, this Apollo 13 series valve is a critical safety upgrade for maintaining compliance with ASME Section IV boiler standards. It is designed for simple installation on steam heating systems, featuring high-strength wrenching surfaces and a bronze safety valve architecture that stands up to continuous thermal cycling and condensate exposure.

• ASME Section IV Certified: National Board rated at 15 PSI for dedicated low-pressure steam service.
• High Relieving Capacity: Delivers 410 PPH (Pounds Per Hour) to handle rapid overpressure events in small to medium boilers.
• Durable Bronze Construction: Built with ASTM B584 bronze and a stainless steel spring for long-term resistance to scale and corrosion.
• Positive Seal Technology: Features a PTFE-faced disc and elevated seating area to ensure a secure shut-off after discharge.
• Compact Top Discharge: The 3/4" MNPT inlet and top outlet configuration allow for streamlined piping in tight mechanical rooms.

• What is the maximum operating temperature for this valve? This 13 Series valve is rated for saturated steam service up to 250°F.
• Can this relief valve be used for hot water heating applications? No, the 13-101-B15 is specifically a Section IV steam valve. For water service, an HV-rated safety relief valve is required.
• Is the discharge capacity certified? Yes, the 410 PPH capacity is National Board certified at the 15 PSI set point.
