Conbraco 19-KFEA-100 Valve

The Conbraco 19-KFEA-100 is an industrial-grade ASME Section I steam pressure relief valve engineered for power boiler applications and high-pressure steam systems. This 1" MNPT inlet x 1 1/4" FNPT outlet valve is factory-set at 100 PSI, providing a discharge capacity of 1,798 lbs/hr. Built with a rugged brass trim and a high-performance Teflon (PTFE) seat, it ensures a positive seal and resistance to scale buildup. The National Board certified design features a top-guided construction and a stainless steel spring to maintain set pressure consistency under thermal cycling. Ideal for steam process equipment and boiler headers, this Apollo 19 series valve provides critical overpressure protection while meeting strict ASME safety valve standards. Its high-capacity flow design minimizes pressure drop during discharge, ensuring system stability for contractors and facility engineers maintaining high-pressure steam safety protocols in commercial or industrial mechanical rooms.

• ASME Section I Certified: Specifically rated for power boiler pressure relief and high-pressure steam service.
• Enhanced Sealing: Features a Teflon PFA seat for superior leak resistance and simplified maintenance compared to metal-to-metal seats.
• Durable Construction: Heavy-duty bronze body and brass trim provide corrosion resistance in harsh boiler room environments.
• High Discharge Capacity: Rated for 1,798 lbs/hr, making it suitable for significant steam loads and large-scale thermal systems.

What is the difference between an ASME Section I and Section VIII valve?
ASME Section I valves, like the 19-KFEA-100, are specifically engineered and certified for power boilers and high-pressure steam piping, whereas Section VIII valves are rated for general pressure vessels.

Can the 100 PSI set pressure be adjusted in the field?
No, these valves are factory-set and sealed. Tampering with the set pressure voids the ASME certification and can lead to dangerous system failures.

Is this valve compatible with heating-only low-pressure boilers?
This valve is designed for high-pressure steam (Section I). For low-pressure steam heating (15 PSI), a Section IV rated valve is generally required by local mechanical codes.
