Danfoss 068U2030 TXV

The Danfoss 068U2030 is a high-performance TUB series thermostatic expansion valve designed for precise refrigerant injection in R134a and R513A systems. This stainless steel TXV features a 1/4" solder ODF inlet and a 1/2" solder ODF outlet, providing a robust, hermetic solution that eliminates the need for wet-wrapping during the brazing process. Engineered with a fixed orifice size 04, the 068U2030 offers an internally equalized design and a nominal capacity of 0.59 TR (2.1 kW), ensuring stable superheat control across a wide temperature range of -40°F to +50°F. Its bi-metal steel/copper connections and 31-inch capillary tube make it a preferred choice for technicians seeking a vibration-resistant, OEM Danfoss expansion valve for light commercial refrigeration, food retail, and specialized cooling applications. This R134a expansion valve is built to withstand a maximum working pressure of 500 psig, maintaining system efficiency under variable load conditions.

• Bi-Metal Connections: Simplifies installation with fast, easy soldering directly to copper lines without the risk of heat damage to the valve body.
• Corrosion Resistance: The stainless steel construction provides superior durability in harsh environments compared to standard brass valves.
• Internal Equalization: Streamlines piping requirements for systems without high-pressure drops across the evaporator.
• Stable Regulation: Precise flow control prevents liquid slugging and evaporator starve-outs, protecting your compressor.
• Compact Design: Small footprint allows for versatile mounting in tight evaporator cabinets and self-contained units.

Is the superheat adjustable on the 068U2030?
Yes, while the orifice is fixed, the Danfoss TUB series typically features an adjustable superheat setting to fine-tune system performance at the job site.

Can I use this valve with R513A refrigerant?
Yes, the 068U2030 is fully compatible with both R134a and R513A, making it a versatile option for modern low-GWP retrofits.

What is the purpose of the 31-inch capillary tube?
The extended capillary length provides flexibility for remote sensing bulb placement, ensuring accurate temperature readings on the suction line.
