Danfoss 068U2163 Expansion Valve

The Danfoss 068U2163 Expansion Valve is a high-performance 1.0 Ton TXV engineered specifically for precise refrigerant flow control in R410A refrigeration systems. This TU series thermostatic expansion valve features a stainless steel capillary tube and bulb, providing superior durability and corrosion resistance compared to standard copper components. Designed with a 3/8" x 1/2" ODF solder connection, it ensures a leak-proof fit for residential and light commercial air conditioning applications. The straight-through flow pattern and internally equalized design allow for consistent superheat control across varying load conditions. For contractors performing a Danfoss TXV replacement, the 068U2163 offers a compact footprint, making it ideal for tight evaporator coils. This Danfoss TUA/TUAE valve utilizing an ORF 5 orifice size provides the reliability required to maintain system efficiency and protect compressors from liquid slugging while ensuring stable evaporator superheat adjustment during peak demand.

• Stainless steel construction provides enhanced protection against harsh environmental conditions and mechanical stress.
• Laser-welded diaphragm ensures long-term integrity and consistent sensing bulb response.
• Bimetal connectors simplify the brazing process, eliminating the need for wet-rag heat sinking during installation.
• Optimized 1-ton capacity specifically tuned for R410A systems to maximize heat transfer efficiency.
• ORF 5 fixed orifice design delivers predictable flow rates and simplifies inventory management for standard service calls.

What is the primary application for the Danfoss 068U2163?
This valve is designed for 1-ton R410A air conditioning and refrigeration units requiring an internally equalized expansion device with ODF solder connections.

Can the orifice be replaced on this specific model?
Yes, as part of the TUA series, this valve utilizes interchangeable orifices, allowing technicians to fine-tune system capacity if load requirements change.

Are special brazing techniques required for the stainless steel connections?
The bimetal ODF connections are designed for standard brazing, but technicians should always use proper nitrogen purging to prevent internal oxidation.
