Conbraco 19-KHGA-125 Valve

The Conbraco 19-KHGA-125 is a high-capacity ASME Section I steam pressure relief valve engineered specifically for power boiler applications. Featuring a 1-1/2" Male NPT inlet and a 2" Female NPT outlet, this valve is factory set at 125 PSI, delivering a certified flow capacity of 5,609 pounds per hour. Constructed with a heavy-duty brass trim and a precision-lapped Teflon (PTFE) seat, it ensures a positive seal and resists scale build-up in high-temperature environments. This National Board certified safety valve utilizes a top-guided design and a stainless steel spring to maintain set pressure consistency despite thermal cycling. Ideal for contractors servicing steam heating systems or process equipment, it provides reliable overpressure protection where ASME V stamp compliance is mandatory. The rugged bronze body architecture is built to withstand the rigors of mechanical rooms while ensuring high-volume discharge during critical pressure excursions.

Key Benefits

• High Discharge Capacity: Rated for 5,609 lbs/hr to handle significant steam loads in Section I applications.
• Teflon Seat Seal: Provides superior leak resistance and chemical compatibility compared to standard metal-to-metal seats.
• ASME Section I Certified: National Board "V" and "NB" stamps ensure compliance with stringent boiler pressure vessel codes.
• Durability: Rugged bronze body and brass internal trim provide excellent corrosion resistance in steam service.
• Precise Pressure Management: Factory-set at 125 PSI with a stainless steel spring for repeatable pop-action and blowdown.

Frequently Asked Questions

Can this valve be used for Section IV heating boilers?
While functional, this is a Section I valve designed for power boilers. Always verify local jurisdictional codes regarding V-stamp versus HV-stamp requirements for your specific installation.

What is the maximum temperature rating for the Teflon seat?
The Teflon (PTFE) seat insert is typically rated for service up to 406°F, aligning with the saturated steam temperature limits for this pressure class.

Is the 19-KHGA-125 suitable for air or gas service?
This specific model is calibrated and certified for steam service. For air or gas applications, ensure the valve carries the appropriate "UV" or "NB" certifications for those mediums.
