Danfoss 068U2204 Expansion Valve

The Danfoss 068U2204 Expansion Valve is a high-precision TUA series thermostatic expansion valve engineered for light commercial refrigeration and air conditioning systems. This R134a expansion valve (also compatible with R513A) features a compact, stainless steel construction that provides exceptional corrosion resistance in demanding HVACR environments. Designed with a 1/4" x 1/2" ODF solder connection, this straightway valve ensures a leak-free, reliable fit for standard copper piping. As an internally equalized TXV, it excels at maintaining precise superheat control across a broad temperature range of -40°F to +50°F, protecting your compressor from liquid slugging while maximizing evaporator efficiency. This specific model, Danfoss 068U2204, is technically identical to the 068U220400, ensuring seamless integration for contractors seeking a direct drop-in replacement. With its bimetal (stainless steel/copper) connections, it allows for easy brazing without the need for expensive heat-sink materials, making it a staple for technicians prioritizing fast, high-quality installations.

• Durable Stainless Steel Construction: High-grade housing provides longevity and resistance to environmental stressors in commercial settings.
• Optimized Refrigerant Control: Designed specifically for R134a and R513A to ensure stable superheat and peak system performance.
• Efficient Installation: Features 1/4 inch inlet and 1/2 inch outlet ODF solder connections for a secure, professional-grade seal.
• Versatile Application: Capable of handling temperatures from -40°F to +50°F, suitable for a wide variety of refrigeration cabinets and small AC units.
• Interchangeable Parts Program: As part of the Danfoss TUA program, it utilizes interchangeable orifices for precise capacity matching.

Is the Danfoss 068U2204 compatible with refrigerants other than R134a?
