Conbraco 19-KEDA-125 Valve

The Conbraco 19-KEDA-125 is a high-capacity Section I steam pressure relief valve designed specifically for power boiler applications. This ASME Section I safety valve features a 3/4" male NPT inlet and a 1" female NPT outlet, engineered to handle a discharge capacity of 1,404 pounds per hour. Built with a rugged brass trim and Teflon seat, the 19-KEDA-125 ensures a positive seal and reliable pop-action release when system pressure reaches the 125 PSI set point. The National Board certified design utilizes a stainless steel spring for consistent performance under high thermal stress, preventing simmer and minimizing seat leakage. For contractors managing steam heating plants or industrial process boilers, this steam boiler safety relief valve provides the necessary overpressure protection required by local mechanical codes. Its corrosion-resistant internals and precision-machined orifice make it a standard replacement part for maintaining system integrity and operational safety in demanding steam environments.

• ASME Code Compliance: National Board certified for Section I applications, ensuring meeting strict safety standards for power boilers.
• High Discharge Capacity: Rated for 1,404 lbs/hr, providing rapid pressure equalization during overpressure events.
• Durable Seat Design: The PFA Teflon seat provides excellent chemical resistance and prevents the disc from sticking to the nozzle.
• Rugged Construction: Features a heavy-duty brass body and stainless steel springs for long-term durability in high-heat environments.
• Precise Blowdown: Engineered for minimal blowdown, maintaining system pressure without excessive steam loss.

Is the Conbraco 19-KEDA-125 suitable for Section IV hot water boilers?
No, this model is specifically a Section I valve for steam service. For hot water heating boilers, a Section IV rated valve must be used to comply with ASME code requirements.

Can the 125 PSI set pressure be adjusted in the field?
Safety relief valves are factory-set and sealed. Field adjustments are not permitted and will void the ASME certification and nameplate rating; if a different pressure is required, a specifically set valve must be ordered.

What is the difference between the 3/4" inlet and 1" outlet on this valve?
The larger 1" outlet is designed to accommodate the volumetric expansion of steam as it transitions from high pressure to atmospheric pressure, preventing backpressure build-up within the valve body.
