Conbraco 19-KJHA-15 Valve

The Conbraco 19-KJHA-15 Valve is a high-capacity ASME Section I steam safety relief valve designed for critical overpressure protection in low-pressure steam boilers and industrial piping systems. Engineered with a rugged bronze body and brass trim, this J-orifice valve features a 2" Male NPT inlet and a 2 1/2" Female NPT outlet. It is factory set at 15 PSI with a National Board certified flow capacity of 2,035 pounds per hour. The integration of a Teflon (PFA) seat ensures a positive seal that resists vibration and corrosive chemicals while simplifying maintenance for the field technician. Its top-guided alignment and double-ring control system provide maximum performance and adjustability, making it the standard for commercial steam heating systems. As a veterans' choice for reliability, this Apollo 19 series valve includes a wide wrenching hex for efficient installation in tight mechanical rooms and a tapped body drain for managing condensate effectively.

• High-Flow J-Orifice Design: Optimized for rapid pressure relief in ASME Section I applications, handling up to 2,035 lb/hr.
• Durable Material Composition: Features ASTM B584 bronze construction and stainless steel springs for long-term structural integrity.
• Advanced PFA Teflon Seating: Provides a soft-seat seal that prevents simmering and withstands temperatures up to 406°F.
• Contractor-Friendly Installation: Built with a wide wrenching hex to prevent housing damage during high-torque pipe fitting.
• Compliance Certified: National Board capacity certified and registered across all Canadian provinces (CRN) for strictly regulated environments.

What systems are compatible with the 19-KJHA-15?
This valve is specifically designed for Section I steam boilers and pressure vessels where the operating pressure does not exceed 15 PSI.

Can the Teflon seat be replaced by a technician?
Yes, the PFA soft seat is designed for easy field replacement, reducing downtime and total repair costs compared to metal-to-metal seating.

Is this valve suitable for air or gas service?
While the 19 series can be used for air/gas, this specific 15 PSI model is optimized and certified for steam pressure relief applications.
