Conbraco 19-MGFA-150 Valve

The Conbraco 19-MGFA-150 is a high-capacity ASME Section I steam pressure relief valve engineered specifically for power boiler applications and pressure piping systems. Built with a 1-1/4" male NPT inlet and 1-1/2" female NPT outlet, this valve features a brass trim and metal seat configuration for durable performance in high-temperature environments. Factory-set at 150 PSI, it delivers a certified discharge capacity of 4,240 pounds per hour. The National Board certified design ensures critical overpressure protection for steam systems where reliability is non-negotiable. Contractors often utilize this 19 series model for its heavy-duty construction and precise blowdown control. When installing, ensure the piping aligns with the side outlet discharge to prevent backpressure issues. This unit meets all ASME V and UV requirements, making it a standard specification for facility maintenance and boiler room upgrades requiring a high-capacity steam safety valve.

• ASME Section I Certified: Specifically rated for power boiler service to ensure code compliance on the job site.
• High Steam Flow Capacity: Rated at 4,240 lbs/hr to handle significant overpressure events in industrial steam systems.
• Rugged Metal Seating: Provides a reliable seal and longevity compared to soft-seated alternatives in high-heat applications.
• Direct Replacements: Standard NPT sizing allows for straightforward integration into existing steam pressure piping.

What is the difference between Section I and Section VIII valves?
ASME Section I valves like the 19-MGFA-150 are designed specifically for power boilers and must meet stricter requirements for blowdown and lift than Section VIII valves used for general pressure vessels.

Can this valve be used for liquid service?
No, this is a dedicated steam pressure relief valve. Using a Section I steam valve for liquid or air medium will result in inaccurate trim performance and potential system failure.

How should the discharge piping be sized?
The discharge piping must be at least equal to the 1-1/2" outlet size and should be supported independently to avoid putting mechanical stress on the valve body.
