Kunkle Valve 6021DCT01AAM0150 Valve

The Kunkle Valve 6021DCT01AAM0150 is a high-performance ASME Section I steam safety relief valve designed specifically for overpressure protection in steam boilers, generators, and pressure-reducing stations. This 1/2" MNPT x 3/4" FNPT side-outlet valve features a Teflon (PFA) disc insert, providing exceptional leak-free performance and superior seating integrity compared to standard metal-to-metal seats. With a set pressure of 150 PSIG and a flow capacity of 926 PPH, it is engineered to handle rigorous industrial steam applications up to 406°F.

Built with a heavy-duty bronze body and a stainless steel spring, the 6021DC series utilizes dual control rings for precise adjustability of opening pressures and exact blowdown control. The 6021DCT01AAM0150 incorporates a grooved piston-type disc to minimize friction and a pivot design between the disc and spring to correct for side thrust, ensuring consistent vertical alignment. For contractors, the wide hex on the valve nozzle allows for straightforward installation using standard tools, making it a reliable choice for maintaining code compliance in HVACR and process steam systems.

• ASME Section I & VIII Certified: Meets National Board standards for V and UV code stamps, ensuring compliance for steam and pressure vessel applications.
• Enhanced Sealing: The Teflon (PFA) seat offers a tight shutoff across multiple cycles, reducing maintenance requirements and steam loss.
• Precise Blowdown Control: Features adjustable dual control rings to manage simmer and ensure sharp opening at the 150 PSI set point.
• Durable Construction: Heavy-duty bronze casting and corrosion-resistant stainless steel springs provide longevity in high-temperature steam environments.
• Ease of Testing: Equipped with a plain lift lever for manual periodic testing as required by safety protocols.

What is the maximum operating temperature for this Kunkle valve?
The 6021 series is rated for a maximum temperature of 406°F, making it suitable for saturated steam service within its pressure range.

Can this valve be used for liquid or air service?
While the 6000 series includes models for air/gas, the 6021 model with the Teflon insert is specifically optimized for steam service to ensure maximum seat life and performance.

Is the discharge piping size critical for this relief valve?
Yes, the 3/4" FNPT outlet must be connected to discharge piping that is self-draining and at least equal to the outlet size to prevent backpressure from affecting the 926 PPH relieving capacity.
