Kunkle Valve 6021EDT01-AM0150 Relief Valve

The Kunkle Valve 6021EDT01-AM0150 is a high-capacity ASME Section I steam safety valve designed for power boiler applications and pressure piping systems. Built with a 3/4" MNPT inlet and a 1" FNPT outlet, this model is factory-set at 150 PSI, delivering a flow capacity of 1651 lbs/hr. Its construction features a bronze/brass trim and a precision-engineered metal seat with a Teflon (PFA) insert, ensuring a tight seal and excellent chemical resistance at high temperatures. The inclusion of a plain lever allows for manual testing, essential for maintaining compliance with safety inspections. Contractors often specify the Kunkle 6021 series for its heavy-duty casting and reliability in demanding steam environments. This industrial relief valve provides consistent overpressure protection, making it a standard choice for boiler pressure relief where high discharge rates are critical for system integrity.

• ASME Section I Certified: Specifically rated for V-stamp steam applications and power boilers.
• Enhanced Sealing: Features a metal seat with a Teflon (PFA) insert to prevent simmering and seat leakage.
• High Flow Rate: Engineered to handle a capacity of 1651 PPH at the 150 PSI set point.
• Durable Construction: Heavy-duty bronze body and brass trim provide superior corrosion resistance in steam service.
• Standard Pipe Connections: 3/4-inch male NPT inlet x 1-inch female NPT outlet for straightforward manifold or boiler installation.

Is the Kunkle 6021EDT01-AM0150 suitable for Section IV hot water boilers?
No, this specific model is a Section I steam relief valve. For hot water heating boilers, a Section IV rated valve is required to meet code compliance.

Can the 150 PSI set pressure be adjusted in the field?
Steam safety valves are factory-sealed to maintain their ASME certification. Any field adjustments to the set pressure would void the certification and compromise safety standards.

What is the purpose of the plain lever on this model?
The plain lever is designed for manual lift testing. National Board inspection codes typically require periodic manual testing to ensure the valve disc is not stuck to the seat.
