Danfoss 067B2790 Orifice

The Danfoss 067B2790 is a precision-engineered TE 5 orifice assembly designed for high-performance thermostatic expansion valves. As an Orifice No. 02, it provides specific refrigerant flow control to ensure optimal evaporator feed and superheat management. This component is compatible with a variety of Danfoss TLE, TLES, and TE 5 valve bodies, a common requirement when servicing commercial refrigeration systems and HVAC chillers. Built with durable materials to resist wear in high-pressure environments, the 067B2790 ensures stability across fluctuating load conditions. Technicians rely on the Danfoss TE 5 series for its interchangeable orifice design, which simplifies capacity adjustments without necessitating a full valve replacement. When completing a refrigeration valve repair, checking the sizing and seating of the 67B2790 is critical to preventing liquid floodback or starving the coil. This orifice is suitable for R404A, R507, R134a, and R22 applications depending on the specific valve body and power head configuration.

• Precise Flow Modulation: The No. 02 orifice size allows for fine-tuned refrigerant metering in TE 5 expansion valves.
• Service Interchangeability: Easily swappable design reduces downtime during HVAC system maintenance and capacity upgrades.
• Robust Construction: Engineered to withstand the rigors of industrial cooling and high-cycling applications.
• System Efficiency: Maintains accurate superheat settings to protect compressors and maximize heat transfer efficiency.

Is the Danfoss 067B2790 compatible with R410A systems?
Compatibility depends on the TE 5 valve body and element rating; always verify the maximum working pressure (MWP) of the valve assembly against R410A operating pressures.

How do I identify if a TE 5 orifice needs replacement?
Inspect for debris buildup, wire-drawing on the needle seat, or signs of erosion that prevent the valve from maintaining a stable superheat setpoint.

Does this orifice include the filter screen?
The 067B2790 is the orifice insert; technicians should verify the condition of the existing strainer or replace it to protect the new orifice from contaminants.
