Danfoss 068U1035 Orifice Assembly

The Danfoss 068U1035 Orifice Assembly is a high-precision internal component engineered specifically for TUA and TUAE thermostatic expansion valves. As a Size 05 orifice, this assembly provides critical metering accuracy to maintain the superheat balance in commercial refrigeration and air conditioning systems. Designed for technicians who require multi-refrigerant compatibility, the 068U1035 is rated for use with a broad range of fluids, including R410A, R404A, R134a, R32, and R452A. This Danfoss TUA orifice features a stainless steel filter and a replaceable design that allows for rapid capacity adjustments without removing the valve body from the line. With a rated capacity of 5.9 kW for R410A and 2.7 kW for R134a, this expansion valve orifice ensures stable performance across a temperature range of -40°F to 50°F. Its straightway flow direction and durable metallic construction make it a standard choice for maintaining 0.78 to 1.7 TR systems.

• Broad Application Versatility: Fully compatible with over 20 refrigerants, including low-GWP options like R454C and R1234yf.
• Interchangeable Design: Allows for quick capacity changes or maintenance in Danfoss TUAE valves without disturbing the brazed connections.
• Debris Protection: Includes an integrated strainer to protect the orifice from system contaminants and ensure long-term flow accuracy.
• Compact and Efficient: Optimized for small-to-medium commercial evaporators requiring precise refrigerant flow control.

What valves is the 068U1035 compatible with?
This orifice is designed exclusively for the Danfoss TUA (stainless steel, flare/solder) and TUAE (stainless steel with external equalization) series thermostatic expansion valves.

Can I use this orifice for R410A systems?
Yes, the 068U1035 is rated for R410A with a capacity of approximately 1.7 TR (5.9 kW), provided the valve body matches the system requirements.

Does this assembly include the filter?
Yes, the orifice assembly comes with the mesh strainer to prevent clogging of the metering port.
