Conbraco 19-KFEA-125 Valve

The Apollo Conbraco 19-KFEA-125 is a high-capacity ASME Section I steam pressure relief valve designed for critical overpressure protection in steam power boilers and pressure piping systems. Engineered with a 1" Male NPT inlet and a 1 1/4" Female NPT outlet, this valve is factory set at 125 PSI with a National Board certified flow capacity of 2,191 pounds per hour. The 19 Series utilizes a rugged bronze body and brass trim, featuring a Teflon PFA seat to ensure positive shut-off and resistance against corrosive boiler chemicals and mechanical vibration.

For veteran contractors, the 19-KFEA-125 valve provides reliable performance with its top-guided alignment and dual control rings, allowing for precise adjustment and a short, "tuned" blowdown to minimize product loss. This safety relief valve is essential for compliance in utility and industrial segments, meeting ASME Section I and VIII requirements for steam, air, and non-hazardous gas service. The unit including stainless steel springs as standard, ensuring consistent set point overpressure protection even in demanding thermal environments up to 406°F.

• ASME Section I Certified: National Board capacity certified for steam power boilers and high-pressure steam systems.
• Enhanced Seat Tightness: The Teflon PFA seat provides superior sealing compared to metal-to-metal designs, reducing leakage and simmer.
• High Flow Efficiency: Delivers a 2,191 PPH capacity through a full-nozzle design, optimized for rapid pressure evacuation.
• Durable Construction: Built with a corrosion-resistant bronze body and brass trim for long-term service in steam applications.
• Simplified Installation: Features a wide wrenching hex for efficient mounting on boiler headers or pressure vessels.

What is the recommended operating pressure for a 125 PSI set valve?
To maintain seat integrity and prevent premature simmering, the system operating pressure should not exceed 90% of the valve's set pressure (112.5 PSI). Maintaining this 10% margin is standard practice for Apollo 19 series valves.

Can this valve be used for liquid service?
No. The Conbraco 19-KFEA-125 is a safety valve specifically designed for compressible fluids like steam and air. Using it for liquid service will result in improper lift and potential system damage.

How should the discharge piping be configured?
Discharge piping must be at least the same size as the 1 1/4" FNPT outlet. It should be as short and straight as possible, independently supported to avoid stress on the valve body, and piped to a safe location or floor drain.
