Danfoss 068-2003 Orifice

The Danfoss 068-2003 is a precision-engineered #00 orifice assembly designed for use within the T2 and TE2 series thermostatic expansion valves. This high-accuracy metering component is essential for maintaining stable superheat and maximizing evaporator efficiency in commercial refrigeration and air conditioning systems. As a veteran-grade replacement part, the Danfoss 068-2003 T2 Style Orifice (also identified as 068-200300) is compatible with a wide array of refrigerants, including R22, R134a, R404A, R407C, R507A, and newer blends like R513A. It features a robust design capable of operating across a broad temperature range from -40°F to 50°F. The orifice includes an integrated dirt-protection filter to prevent debris from compromising the valve seating, ensuring long-term reliability in the field. For technicians performing refrigerant flow control adjustments, this interchangeable orifice allows for field-ready capacity matching without replacing the entire valve body.

• Precise Capacity Matching: Specifically sized as #00 orifice to deliver accurate refrigerant metering for low-tonnage applications.
• Broad Refrigerant Compatibility: Engineered for use with R22, R134a, R404A/R507, R407C, and more.
• Enhanced System Reliability: Features an integral filter to protect the expansion valve seat from system contaminants.
• Installation Versatility: Designed for SAE flare connections, making it a standard choice for Danfoss T2 valve bodies in the field.
• Technical Interchangeability: This part is the direct equivalent to 068-200300, ensuring zero-clearance compatibility during service.

Common Questions

What is the nominal capacity of the Danfoss #00 orifice?
The nominal capacity of the 068-2003 typically ranges from 0.34 TR to 0.51 TR depending on the refrigerant used (e.g., approximately 0.5 tons for R22 and 1.2 kW for R134a under standard conditions). Always consult the Danfoss capacity chart for specific evaporator temperatures.

Is the 068-2003 compatible with TE2 valve bodies?
Yes, the Danfoss 068-2003 is designed for both T2 (internal equalization) and TE2 (external equalization) brass body thermostatic expansion valves.

Can I use this orifice for both freezing and air conditioning?
Yes, this T2 style orifice is rated for Range N (-40°F to 50°F), making it suitable for a variety of refrigeration and HVAC applications.
