Danfoss 068U1030 Orifice Assembly

The Danfoss 068U1030 (also identified as 068U103000) is a precision-engineered orifice assembly designed specifically for the TUA and TUAE series thermostatic expansion valves. This size 00 orifice is essential for managing the flow of liquid refrigerant into the evaporator, ensuring accurate superheat control across varying load conditions. It is optimized for use with environmentally friendly refrigerants including R134a, R404A, R407C, and R410A. The stainless steel construction provides superior durability against erosion and contaminants, which is critical for maintaining long-term system stability. As a replaceable orifice design, it allows for easy field servicing and capacity matching without requiring the removal of the valve body from the line. For technical installations, ensure the bimetal connections on the TUA valve body are protected, although the orifice itself is a mechanical drop-in component. Utilizing a Danfoss TUA orifice ensures that your HVAC expansion valve maintains peak volumetric efficiency and prevents liquid slugging in the compressor.

• Broad Refrigerant Compatibility: Designed to function reliably with R410A, R407C, R134a, and R404A systems.
• Interchangeable Design: The 068U103000 allows for rapid capacity adjustments in the field without breaking brazed joints.
• Precision Metering: Size 00 bore provides exact mass flow rates required for low-capacity refrigeration and AC applications.
• Corrosion Resistance: High-grade stainless steel internal components resist wire-drawing and chemical degradation.

Is the 068U1030 compatible with flare or solder TUA valves?
Yes, this orifice assembly is designed to fit the internal cage of both solder and flare configurations of the TUA/TUAE valve series.

What is the difference between 068U1030 and 068U103000?
They are the exact same part; the "00" suffix is often used in Danfoss logistics for packaging variants, but the technical specifications are identical.

Does this orifice include the filter screen?
This assembly typically includes the orifice insert; however, it is recommended to inspect or replace the external filter screen during any TXV service to ensure unobstructed refrigerant flow.
