Conbraco 19-KHGA-15 Valve

The Conbraco 19-KHGA-15 is a high-capacity ASME Section I steam pressure relief valve engineered for power boiler applications where reliable overpressure protection is critical. This 1-1/2 inch MNPT x 2 inch FNPT valve is factory-set at 15 PSI, delivering a discharge capacity of 1,240 pounds per hour. Constructed with a rugged bronze body, it features brass trim and a Teflon (PTFE) seat to ensure positive shut-off and resistance to scale build-up. The high-discharge design facilitates rapid pressure equalization in low-pressure steam systems. Designed for durability in demanding mechanical rooms, this Apollo 19 series valve meets strict National Board capacity certifications. Contractors utilize this model for its consistent lift characteristics and repeatable performance. It is an essential component for maintaining system integrity in accordance with jurisdictional boiler codes, providing a robust solution for steam safety relief in commercial and industrial piping remains.

• ASME Section I Certified: Specifically rated for power boiler applications ensuring compliance with safety standards.
• High Discharge Capacity: Rated at 1,240 lbs/hr to handle significant steam volume during overpressure events.
• Teflon Seat: Provides a superior seal and prevents the disc from sticking to the seat due to mineral deposits.
• NPT Connections: Standard 1-1/2" male inlet and 2" female outlet allow for straightforward integration into existing pipe headers.
• Top-Guided Design: Features an alignment-stable disc and stem to ensure consistent re-seating after discharge.

What is the difference between Section I and Section IV relief valves?
ASME Section I valves, like this Conbraco 19-KHGA-15, are designed for power boilers and high-pressure steam applications, whereas Section IV valves are intended for low-pressure heating boilers. Section I valves undergo more rigorous testing for high-temperature durability.

Can this valve be mounted horizontally?
No, steam pressure relief valves must be installed in a vertical position with the spindle upright to ensure proper mechanical operation and gravity-assisted drainage of the discharge piping.

Is the 15 PSI setting adjustable in the field?
Pressure relief valves are factory-set and sealed. Field adjustments are not permitted by code as they can compromise the safety rating and invalidate the ASME stamping.
