Danfoss 068U1036 Orifice Assembly

The Danfoss 068U1036 Orifice Assembly is a critical metering component designed specifically for TUA and TUAE series thermostatic expansion valves. As a veteran-grade refrigeration expansion valve orifice, this size 06 assembly ensures precise liquid injection across a broad spectrum of thermal loads. Engineered for high-pressure refrigerant flow control, it is compatible with modern refrigerants including R410A, R32, R404A, R407C, and R134a/R513A, as well as low-GWP alternatives like R1234yf and R454C. The interchangeable design allows technicians to field-service TUA valves without replacing the entire valve body, maintaining system integrity in temperatures ranging from -40°F to 50°F. This multi-pack provides nine stainless steel orifices, ensuring you have the necessary HVACR replacement parts for commercial refrigeration or air conditioning maintenance. Its straightway flow direction and precise machining eliminate hunting issues, ensuring stable superheat and optimized evaporator efficiency in TUA/TUAE expansion valve applications.

Key Benefits for Contractors:

• Universal Refrigerant Compatibility: Supports a comprehensive range of traditional and A2L refrigerants including R410A, R32, and R454C.
• Field Service Efficiency: Designed for rapid exchange within Danfoss TUA/TUAE valve bodies, reducing downtime during capacity adjustments.
• Precision Flow Control: Size 06 orifice geometry provides consistent metering for stable superheat management.
• Industrial Build Quality: Constructed for refrigeration system performance with high resistance to debris and mechanical wear.
• Standardized Compliance: Meets EAC and LLC CDC TYSK requirements for professional-grade installations.

Common Questions:

Is the Danfoss 068U1036 compatible with all TU series valves?
This orifice is specifically engineered for the TUA and TUAE stainless steel expansion valves. It is not interchangeable with older brass TGE or TRE series assemblies.

Which refrigerants can I use with this size 06 orifice?
It is validated for a wide array of fluids, including R410A, R134a, R32, R404A, R507, R407C, and several HFO/HFO-blends such as R1234ze and R450A.

Does this assembly include the filter and spring?
This orifice assembly 068U1036 is the standard replaceable insert designed for TUA/TUAE valves; always verify your specific valve body's cage and strainer requirements during a tear-down.
