Danfoss 068U2097 Expansion Valve
The Danfoss 068U2097 is a specialized thermostatic expansion valve (TXV) from the Danfoss TUB series, specifically engineered for high-performance thermal regulation in secondary refrigeration and air conditioning systems. This model is built with a robust stainless steel body to provide superior resistance to corrosion and is designed for use in R404A and R507A systems. It features a fixed orifice size 4, delivering a nominal 0.60 ton capacity. The 1/4" x 1/2" ODF solder connections (angleway) ensure reliable, leak-free integration with bimetal steel/copper jointing technology. Technicians will find the adjustable superheat setting critical for fine-tuning system efficiency, while the internally equalized design simplifies installation in units without external pressure taps. Identical to the Danfoss 068U209700, this valve supports a wide temperature range of -40°F to 50°F (-40°C to 10°C) and is rated for a maximum working pressure of 500 psig, making it a dependable choice for commercial evaporators and ice machines.
Key Benefits for Contractors- Corrosion Resistance: High-grade stainless steel construction ensures longevity in harsh environments compared to standard brass bodies.
- Precise Flow Control: Equipped with an adjustable superheat spindle to optimize evaporator performance and prevent liquid floodback.
- Streamlined Installation: Compact angleway design with 31-inch capillary tube and included bulb strap for thermal response stabilization.
- Broad Compatibility: Rated for R404A/R507A refrigerants, common in low and medium-temperature commercial refrigeration.
- High Pressure Rating: Safely handles up to 500 psig (34 bar), suitable for modern high-pressure refrigeration cycles.
- What is the difference between 068U2097 and 068U209700? These are identical part numbers; the "00" suffix is often used in Danfoss logistics but refers to the same 0.60 ton TXV.
- Does this valve require an external equalizer line? No, the Danfoss 068U2097 is internally equalized, making it ideal for systems that do not have a pressure drop across the evaporator.
- Can this be used with R22 or R134a? This specific model is factory-charged and calibrated for R404A and R507A; using other refrigerants will result in incorrect superheat and potential compressor damage.
