Danfoss 068U2285 Expansion Valve

The Danfoss 068U2285 Thermostatic Expansion Valve is a TUA-type expansion valve specifically engineered for high-performance refrigerant metering in R404A and R507A systems. Featuring a 3/8" x 1/2" ODF solder connection, this internally equalized TXV ensures stable evaporator superheat across a broad temperature range of -40°F to +50°F. Its construction utilizes a stainless steel body paired with bi-metal steel/copper connections, allowing for high-strength brazing without the need for additional cooling wet-rags. Designed for commercial refrigeration and industrial cooling, the Danfoss 068U2285 supports a maximum working pressure of 500 psig (34 bar). The 59-inch capillary tube provides significant flexibility for bulb placement, while the adjustable superheat setting allows technicians to fine-tune system efficiency on-site. This straightway flow valve includes a laser-engraved orientation arrow to prevent installation errors in demanding field environments.

Key Benefits for Contractors

• Corrosion Resistance: The stainless steel power element and capillary tube provide superior durability in harsh environments compared to traditional brass valves.
• Optimized Flow Control: The internally equalized design simplifies installation in systems without significant pressure drops across the evaporator.
• Precision Tuning: Adjustable superheat allows for exact calibration to meet specific load requirements and prevent liquid slugging.
• Simplified Brazing: Bi-metal connections facilitate faster, more reliable joints during HVACR refrigeration valve replacement.
• Wide Application Range: Compatible with both R404A and R507A refrigerants, making it a versatile stock item for commercial walk-ins and reach-in coolers.

Common Questions

Is the orifice included with the Danfoss 068U2285?
The TUA series typically utilizes interchangeable orifice assemblies. Verify your specific capacity requirements to ensure the correct orifice size is paired with this valve body.

Can this valve be used with R134a or R22?
No, this specific model (068U2285) is charged specifically for the pressure-temperature characteristics of R404A and R507A. Using it with other refrigerants will result in improper superheat control and potential compressor damage.

What is the purpose of the 59-inch capillary tube?
The extended length allows for the thermal bulb to be mounted securely on the suction line even in compact or crowded evaporator housing configurations.
