Danfoss 068U2028 TXV

The Danfoss 068U2028 is a high-performance TU series thermostatic expansion valve designed for precise superheat control in refrigeration and air conditioning systems. This stainless steel TXV features a 1/4" x 1/2" ODF solder connection and utilizes orifice 2 to deliver a nominal capacity of 0.28 tons. Built to withstand demanding environments, it incorporates a laser-welded sensing element for long-term diaphragm integrity and consistent performance across varying ambient temperatures. The valve is optimized for R134a and R404A refrigerants, though technicians should verify charge requirements for specific applications. Its compact design facilitates installation in tight evaporators, and the bi-metal connections allow for fast brazing without the need for extensive heat-sink measures. This Danfoss expansion valve ensures stable evaporator feeding, maximizing heat transfer efficiency and protecting compressors from liquid slugging in commercial and light industrial systems.

• Stainless Steel Construction: High corrosion resistance and durability compared to traditional brass valves.
• Precise Superheat Regulation: Optimized for maintaining system stability and energy efficiency under changing load conditions.
• Capillary Tube Integrity: Laser-welded components reduce the risk of refrigerant leaks and charge loss.
• Bi-metal Solder Connections: Enables efficient refrigeration brazing without damaging internal valve components.
• Compact Footprint: Ideal for OEM replacements and retrofit applications in restricted spaces.

What is the capacity of the orifice size 2 in the Danfoss 068U2028?
This specific configuration provides a nominal capacity of 0.28 tons, making it suitable for smaller refrigeration loads where precise metering is critical.

Which refrigerants are compatible with this TU valve?
The Danfoss 068U2028 is commonly utilized with R134a, R404A, and R507, but always check the bulb marking and cross-reference the PT chart for your specific refrigerant replacement.

Does this valve require an external equalizer?
The 068U2028 is an internally equalized valve, suitable for systems without significant pressure drops across the evaporator.
