Kunkle Valve 6021JHT01AAM0150 Valve

The Kunkle Valve 6021JHT01AAM0150 is a heavy-duty bronze safety valve engineered for critical overpressure protection in steam boiler applications and industrial pressure vessels. This model features a 2" MNPT inlet and a 2.5" FNPT side outlet, specifically calibrated for a set pressure of 150 PSIG with a flow capacity of 10,818 PPH. Constructed with a robust bronze body and a Teflon (PFA) disc insert, the 6021JHT01AAM0150 ensures leak-free performance and superior seating integrity compared to metal-seated alternatives, particularly in steam service. It utilizes a stainless steel spring and a J-size orifice (1.414 sq. in.) to maintain precise blowdown control through dual control rings. This valve is ASME Section I and Section VIII certified (including V and UV stamps) and is National Board certified, making it a reliable choice for commercial heating, pressure reducing stations, and high-pressure steam generators. The plain lever design allows for manual testing, while the pivot design between the disc and spring compensates for side thrust to prevent premature wear.

Key Performance Benefits

• ASME Certified Reliability: Fully compliant with ASME Section I, IV, and VIII standards for steam and gas, ensuring safety in National Board certified installations.
• Enhanced Sealing: Features a high-grade Teflon (PFA) disc insert for an exceptional tight shutoff, reducing simmer and maintenance costs.
• Precise Operation: Dual control rings allow for exact blowdown control and adjustability for precise opening pressures with minimal pre-open.
• Industrial Durability: Heavy-duty bronze casting and stainless steel spring support a broad temperature range from -60°F up to 406°F.
• Ease of Installation: Designed with a wide hex on the valve nozzle for better wrenching clearance during piping.

Common Contractor Questions

What is the difference between the 6021JHT01AAM0150 and the 6021JHT01-AM0150?
These part numbers represent the same technical specification. The "AAM" designator is often used in modern inventory systems to indicate standard revision A, providing the exact same 2" x 2.5" 150 PSI steam relief performance.

Can this valve be used for air or gas service?
Yes, while the 6021 model is optimized for steam with its Teflon disc, it is also PED certified for non-hazardous gases and holds the ASME Section VIII UV stamp for air and gas applications.

What Kunkle models is this unit compatible with for replacement?
As a 2" x 2.5" safety valve, it is a direct replacement or high-spec alternative for various 6000 series configurations and is compatible where models 6933, 6934, or 6935 are specified under ASME Section IV requirements.
