Conbraco 19-EDCL-40 Valve

The Conbraco 19-EDCL-40 is a heavy-duty ASME Section VIII certified steam safety valve designed for precision overpressure protection in industrial and commercial steam systems. As a veteran-grade pressure relief valve, it features a 1/2" MNPT inlet and 3/4" FNPT outlet configuration with a dedicated D orifice to manage flow dynamics efficiently. This Apollo 19 series valve is factory-set at 40 psig, delivering a certified steam capacity of 327 PPH. Engineered with a rugged ASTM B584 bronze body and stainless steel spring, the unit employs a top-guided alignment design and a high-capacity full nozzle to ensure consistent seating and reliable lift. For service contractors, the wide wrenching hex streamlines installation in tight boiler rooms or piping manifolds. The inclusion of two control rings allows for maximum adjustability and performance, while the short tuned blowdown effectively minimizes product loss during discharge cycles.

• ASME Section VIII & NB Certified: National Board capacity certified for reliable overpressure protection in unfired pressure vessels and steam piping.
• Enhanced Durability: Constructed with a bronze body and stainless steel springs to resist corrosion and thermal fatigue in environments up to 406°F.
• Tapped Body Drain: Integrated 1/8" NPT drain allows for the safe piping of condensate away from the valve seat, preventing scale buildup.
• Simplified Maintenance: Featuring a soft seat (PFA Teflon) design that reduces repair costs and ensures bubble-tight shutoff compared to traditional metal-to-metal seats.
• Precision Performance: The 1/2" x 3/4" configuration with a lift lever actuator provides manual testing capabilities required by most local boiler jurisdictions.

Is the Conbraco 19-EDCL-40 suitable for Section I power boilers?
While the 19 Series is dual-certified for Section I and Section VIII, this specific 19-EDCL-40 model is specifically rated and stamped for ASME Section VIII applications like sterilizers, cookers, and pressure reducing stations.

What is the maximum temperature rating for this steam valve?
Equipped with a PFA Teflon seat, this valve is rated for a maximum temperature of 406°F, making it ideal for saturated steam service within its pressure range.

Can I install this valve in a horizontal orientation?
No. To ensure proper mechanical operation and drainage, this safety valve must be installed in a vertical upright position directly on the pressure vessel or piping nozzle.
