Danfoss 068U2287 Element/Valve

The Danfoss 068U2287 (identical to 068U228700) is a high-performance TUAE Thermostatic Expansion Valve designed for precise liquid injection in refrigeration systems using R404A and R507A refrigerants. This stainless steel TXV features an external equalization connection (1/4" ODF) and is engineered with 3/8" inlet by 1/2" outlet solder ODF connections. Built to handle a maximum working pressure of 500 psig (34 bar), the 068U2287 operates effectively across a wide temperature range from -40°F to 50°F. The bimetal solder connections allow for fast, easy installation without the need for wet-wrapping, while the 59-inch capillary tube provides flexibility for remote bulb placement. As a bi-flow capable valve, it offers exceptional versatility for commercial refrigeration technicians servicing TUA-series systems.

• Corrosion Resistant: The stainless steel body and power element ensure durability in harsh environments compared to traditional brass valves.
• Service Efficiency: Features an exchangeable orifice assembly (compatible with sizes 1-8) for simplified field capacity adjustments.
• High-Stability Control: The TUAE design utilizes a specialized charge to provide stable superheat control even under varying load conditions.
• Thermal Shielding: Laser-welded power element increases the component's life expectancy by reducing stress on the diaphragm.
• Leak Prevention: Hermetically sealed design minimizes potential leak points within the refrigerant circuit.

Does this valve include the internal orifice?
The Danfoss 068U2287 is the element and valve body; the orifice is typically sold separately or as part of a kit depending on your specific tonnage requirements.

Can this be used with R507A without adjustment?
Yes, it is rated for both R404A and R507A. However, fine-tuning the adjustable superheat is recommended during commissioning to ensure peak evaporator efficiency.

What is the benefit of the bimetal connections?
Bimetal connections allow techicians to braze the valve into the line without using a heat sink or wet rag, significantly reducing installation time and protecting the internal components from heat damage.
