Danfoss 068U4280 Element/Valve
The Danfoss 068U4280 is a high-performance TCAE thermostatic expansion valve element designed for precise refrigerant metering in commercial air conditioning and refrigeration systems. Engineered with a stainless steel power element and a bi-metal solder connection (steel/copper), this externally equalized valve ensures reliable superheat control across a wide temperature range of -40°F to +50°F. This specific TXV expansion valve is optimized for R22 and R407C refrigerants, featuring a 3/8" ODF inlet and a 5/8" ODF outlet. With a maximum working pressure of 660 psig (45.5 bar) and a 59-inch capillary tube, it provides the flexibility needed for various evaporator configurations. The externally equalized design compensates for pressure drops across the evaporator, maintaining system efficiency and protecting the compressor from liquid slugging. Contractors can rely on this Danfoss refrigeration part for straightway flow direction and bi-flow capability when paired with the appropriate orifice from the TCA parts program.
Key Benefits- Corrosion Resistance: Durable stainless steel body and laser-welded diaphragm ensure long-term hermetic integrity.
- Installation Efficiency: Bi-metal connections allow for fast, easy soldering without the need for heavy wet-ragging.
- Operational Stability: External equalization provides accurate superheat adjustment, even in systems with significant high-side pressure drops.
- Versatile Compatibility: Designed specifically for R22 refrigerant and R407C cooling systems.
Is the orifice included with the 068U4280 element?
No, this is the thermostatic element and valve body only. The orifice is part of a separate parts program, allowing you to size the capacity specifically to your system requirements.
What is the purpose of the 1/4" external equalization line?
The 1/4" solder connection allows the valve to sense pressure at the evaporator outlet, ensuring the thermostatic expansion valve maintains the correct superheat regardless of internal pressure drops.
Can this valve be used in bi-flow applications?
Yes, the TCAE series is designed for bi-flow operation when using orifice sizes 1 through 2, making it suitable for heat pump applications.
