Conbraco 19-KJHA-150 Valve

The Conbraco 19-KJHA-150 is a high-capacity ASME Section I steam pressure relief valve designed specifically for power boiler applications. This model features a 2" Male NPT inlet and a 2 1/2" Female NPT outlet, engineered to handle a set pressure of 150 PSI. With a discharge capacity of 10,864 pounds per hour, it provides critical overpressure protection for heavy-duty steam systems. The internal construction utilizes a brass trim and a Teflon seat, ensuring a positive seal and reliable popping action under thermal load. The rugged bronze body is built to withstand rigorous mechanical stress in industrial environments. This National Board certified valve is a direct replacement for Apollo 19 series configurations requiring precise blowdown control and repeatable performance. For contractors and plant engineers, the 19-KJHA-150 represents a standard in boiler safety valve compliance and system integrity.

• High Flow Capacity: Delivers 10,864 lbs/hr displacement for rapid pressure stabilization.
• Reliable Sealing: Integrated PTFE (Teflon) soft seat prevents simmer and leakage at high operating pressures.
• ASME Compliance: Meets strict Section I Power Boiler codes for legal and safe operation.
• Durable Metallurgy: High-strength bronze body with brass internals resists corrosion in steam environments.
• Maintenance Ready: Standard NPT connections allow for straightforward field installation and replacement.

What is the difference between Section I and Section IV relief valves?
Section I valves, like the 19-KJHA-150, are rated for power boilers and high-pressure steam exceeding 15 PSI, whereas Section IV valves are intended for low-pressure heating boilers.

Can this valve be mounted horizontally?
No, this steam relief valve must be installed in a vertical upright position to ensure correct mechanical operation and drainage of the discharge piping.

Is the blowdown adjustable on the 19-KJHA-150?
Yes, as a Section I valve, it features an adjustable blowdown ring to control the pressure drop required before the valve re-seats.
