Danfoss 067N9411 Expansion Valve
The Danfoss 067N9411 Thermal Expansion Valve is a high-capacity TGEX 20 series TXV designed for precise refrigerant metering in commercial air conditioning and refrigeration systems. This 15-ton expansion valve features a straight-body configuration with 5/8" ODF inlet and 1 1/8" ODF outlet connections, facilitating a secure solder joint for high-pressure applications. Engineered for R22 and R407C refrigerants, this valve includes an externally equalized 1/4" ODF connection to compensate for evaporator pressure drop, ensuring optimal superheat control. The integrated #16 orifice provides consistent flow modulation, while the 60-inch capillary tube allows for flexible bulb placement on the suction line. This unit acts as the direct technical replacement for Danfoss 068H7140, maintaining a Max Operating Pressure (MOP) of 667 PSI. For contractors managing Danfoss expansion valve replacement, the TGEX 20 platform offers a balanced ported design that remains stable across varying head pressures and evaporator loads.
Key Benefits:- Dual Refrigerant Compatibility: Optimized for high-pressure R22/R407C thermal expansion valve applications.
- Precise Superheat Control: Features an adjustable static superheat setting to prevent liquid slugging and maximize evaporator efficiency.
- Enhanced Durability: Stainless steel power element and capillary tube provide superior corrosion resistance in harsh mechanical environments.
- Direct Retrofit: Seamlessly replaces the legacy Danfoss 068H7140 without requiring piping modifications.
- Reliable Sealing: Laser-welded diaphragm ensures a long service life and prevents refrigerant leakage at the power head.
Is the 067N9411 compatible with R410A systems?
No, this specific TGEX 20 TXV is calibrated for the pressure-temperature curves of R22 and R407C only. Using it with R410A will lead to improper metering and potential system failure.
What is the purpose of the 667 PSI MOP rating on this valve?
The Maximum Operating Pressure (MOP) protects the compressor motor against overload during start-up or after defrost by limiting the suction pressure within safe parameters.
Does this valve require a separate orifice assembly?
No, the Danfoss 067N9411 comes with a fixed #16 orifice optimized for a 15-ton nominal capacity, simplifying the installation process for the technician.
