Conbraco 19-KJHA-50 Valve
Technical contractors looking for a dependable overpressure solution for Section I power boilers will find the Conbraco 19-KJHA-50 Valve a standard-setting choice. This ASME Section I steam safety valve features a 2" Male NPT inlet and a 2 1/2" Female NPT outlet, specifically engineered for high-capacity discharge. With a set pressure of 50 PSI and a certified capacity of 4,283 pounds per hour, this bronze-bodied valve ensures critical system protection. The 19-KJHA model utilizes a Teflon PFA soft seat and brass trim, offering superior seat tightness and resistance to the corrosive chemicals common in boiler feed water. Its dual-control ring design allows for precise blowdown adjustment, minimizing steam loss during actuation. The heavy-duty stainless steel spring maintains consistent set pressure across a temperature range of -60°F to 406°F. For field serviceability, the soft seat is designed for straightforward replacement, significantly reducing maintenance downtime on the mechanical floor.
Key Benefits for Contractors- ASME National Board Certified: Rated for Section I (V) steam applications, ensuring compliance with strict pressure vessel safety codes.
- Enhanced Sealing: The PFA Teflon seat provides a bubble-tight seal that resists vibration and prevents simmering at 90% of set pressure.
- Optimized Flow: High-capacity 4,283 PPH discharge rate protects large-scale boiler systems from catastrophic overpressure events.
- Installation Ready: Features a wide wrenching hex and a 3/8" NPT tapped body drain to simplify the piping of condensate away from the valve.
What is the difference between a safety valve and a relief valve in steam service?
In high-pressure steam systems, a safety valve like the 19-KJHA-50 is designed for rapid, full-opening actuation to dump volume quickly. A relief valve typically opens in proportion to the pressure increase and is more common in liquid applications.
How do I handle the discharge piping for a 2 1/2" outlet?
Always use Schedule 40 pipe for the discharge line. Ensure the piping is supported independently so no weight or stress is placed on the valve body, and always include a drip pan elbow to manage condensate.
Can I install this valve horizontally?
No. ASME code requires that safety valves be mounted in a vertical, upright position. Installing the spindle in any other orientation will cause internal friction, affecting the set pressure and performance.
