Danfoss 068U2075 Expansion Valve

The Danfoss 068U2075 is a high-performance TU expansion valve designed for reliability in R22 refrigeration systems. This thermostatic expansion valve features a 3/8" x 1/2" flare connection and an integrated 09 orifice, providing precise superheat control. Built with a stainless steel power element and laser-welded construction, it offers superior corrosion resistance and longevity in demanding HVACR environments. The internal equalization design simplifies installation by eliminating the need for an external balance line, making it a drop-in solution for many commercial refrigeration and air conditioning evaporators. This TXV for R22 ensures stable evaporator feeding across a range of load conditions, protecting the compressor from liquid slugging while maintaining optimal system efficiency. The Danfoss TUA/TU valve series is recognized for its thermal stability and low heat conduction from the power element to the valve body, ensuring consistent performance regardless of ambient temperature fluctuations during the R22 expansion valve replacement process.

• Stainless Steel Construction: High resistance to corrosion and capillary tube fatigue ensures durability in harsh field conditions.
• Bimetal Connections: Facilitates fast, easy soldering without the need for extensive heat sinking or wet rags.
• Internal Equalization: Reduces installation time and potential leak points by removing the requirement for an external pressure line.
• Precise Superheat Regulation: The 09 orifice size provides accurate refrigerant metering for improved evaporator efficiency.
• Serviceability: Compact design allows for easy integration into tight equipment cabinets and mechanical rooms.

Is the Danfoss 068U2075 compatible with synthetic oils?
Yes, while optimized for R22 systems typically using mineral or alkylbenzene oils, the materials in the TU series are compatible with POE oils often found in retrofit applications.

What is the benefit of the flare connection on this specific model?
The 3/8" x 1/2" flare fittings allow for a mechanical connection, which is ideal for quick field replacements where brazing may be restricted or inconvenient.

How does this valve handle varying load conditions?
The Danfoss TU series utilizes a specialized charge in the bulb to provide stable refrigerant flow control across a wide temperature range, minimizing hunting during low-load periods.
