Danfoss 068U1032 Orifice Assembly

The Danfoss 068U1032 Orifice Assembly (Size 02) is a precision-engineered internal component designed for the TUA and TUAE series thermostatic expansion valves. Engineered for high-pressure refrigeration cycles, this Danfoss TUA orifice provides reliable flow control across various evaporative loads. The 068U1032 is cross-compatible and identical to 068U103200, ensuring a seamless drop-in replacement during field repairs or system overhauls. Fabricated with a stainless steel orifice and integrated filter, it effectively manages refrigerant expansion while protecting the valve seat from debris. Technicians frequently specify this TXV orifice replacement for its bi-metal construction, which allows for fast, torch-brazing installations without the need for wet-ragging. Whether managing R22, R134a, or R404A systems, this assembly ensures stable superheat control. Utilizing a high-quality refrigeration metering device like the 068U1032 is critical for maintaining EER and preventing liquid slugging in commercial HVACR applications.

• Interchangeable design: Fully compatible with TUA, TUAE, and TUB/TUBE valve bodies for simplified inventory management.
• Debris Protection: Built-in replaceable filter prevents contaminants from fouling the valve seat, ensuring consistent mass flow.
• Corrosion Resistance: Stainless steel construction offers superior durability against moisture and acidic oil breakdown.
• Thermal Stability: Designed to maintain precise superheat adjustment across a wide range of operating temperatures.

How do I identify the correct orifice size for a TUA valve?
Size is determined by the required cooling capacity (in tons or kW) for your specific refrigerant and evaporating temperature. The 02 size indicates a specific flow coefficient suited for low-to-medium capacity circuits.

Is the Danfoss 068U1032 compatible with both flare and solder connections?
Yes, the orifice assembly is independent of the valve’s external connection type, meaning it fits both solder and flare TUA/TUAE bodies.

What is the difference between 068U1032 and 068U103200?
There is no technical difference; 068U103200 is simply the full 10-digit code used for global logistics, while 068U1032 is the shorthand industry designation.
