Conbraco 19-KEDA-150 Valve

The Conbraco 19-KEDA-150 Valve is a high-performance ASME Section I steam relief valve engineered for critical overpressure protection in power boiler applications and pressure piping systems. Featuring a 3/4" Male NPT inlet and a 1" Female NPT outlet, this National Board certified safety valve delivers a discharge capacity of 1,656 pounds per hour at a 150 PSI set pressure. Designed with a rugged bronze body and brass trim, it utilizes a Teflon (PTFE) seat to ensure positive shut-off and resistance to corrosive boiler chemicals. The top-guided design and stainless steel springs provide stable performance under extreme thermal cycles, with a maximum temperature rating of 406°F. Contractors value the 19-series for its dual-ring control, which allows for precise adjustability and short blowdown, minimizing steam loss during actuation. This durable safety relief valve is essential for maintaining code compliance in industrial steam services and unfired pressure vessels.

Key Benefits

• Code Compliance: Certified to ASME Section I and Section VIII standards, meeting strict safety requirements for power boilers and pressure systems.
• Durable Seating: The Teflon PFA seat resists vibration and chemical degradation, ensuring longevity compared to standard metal-to-metal seats.
• High Flow Efficiency: Features a full-bore design and two control rings for maximum steam discharge capacity and optimal adjustability.
• Heavy-Duty Construction: Built with a corrosion-resistant bronze body and a wide wrenching hex for fast, secure installation by field technicians.
• Condensate Management: Includes a tapped body drain to safely pipe away condensate, preventing accumulation and potential water hammer.

Common Questions

What is the maximum operating temperature for this valve?
The 19-KEDA series is rated for a maximum temperature of 406°F (207°C), making it suitable for high-pressure saturated steam applications.

Can this safety valve be used for air or gas service?
Yes, while certified for Section I Steam, the 19-series is also ASME Section VIII capacity certified for air and non-hazardous gas applications.

Is the seat replaceable if it wears out?
The soft seat design allows for easier maintenance; the PTFE seat is designed to be replaceable, reducing the need for full valve replacement and lowering long-term repair costs.
