Danfoss 067N2163 TGEX TXV

The Danfoss 067N2163 TGEX TXV is a balanced port thermostatic expansion valve engineered for high-capacity air conditioning and heat pump systems. This biflow unit features a 7/8" x 1-1/8" ODF solder connection and is optimized for R22 and R407C refrigerants. As a technical upgrade, the 067N2163 is the direct replacement for 067L1187, ensuring seamless integration into existing commercial HVAC systems. The laser-welded bellows construction enhances the valve's lifespan under high-pressure fluctuations, while the stainless steel power element provides superior corrosion resistance. Technicians will find the adjustable superheat setting critical for fine-tuning system efficiency across varying evaporator loads. The balanced port design is specifically utilized to neutralize the influence of changing head pressures, maintaining stable superheat control even in demanding Danfoss expansion valve replacement scenarios. This part is designed for field-serviceability, allowing for reliable liquid injection control in large-scale installations.

• Biflow Capability: Provides consistent performance in both cooling and heating modes for heat pump applications.
• Laser-Welded Bellows: Extends the mechanical life of the valve compared to traditional soldered power elements.
• Direct Retrofit: Specifically matches the footprint of the legacy 067L1187 for faster field installation.
• Wide Temperature Range: Optimized for medium and high-pressure refrigerant applications including air conditioning and water chillers.

Is the 067N2163 compatible with R407C systems?
Yes, this valve is rated for both R22 and R407C, though superheat adjustments may be required during commissioning to account for refrigerant glide.

What is the primary difference between this and the older 067L series?
The 067N2163 is an updated version that maintains the same physical dimensions and port capacity while improving overall bellows durability.

Does this valve require a specific orientation?
While the biflow design allows for flexibility, the valve should be installed as close to the evaporator inlet as possible to ensure accurate superheat sensing via the bulb.
