Product details
Danfoss TE 2 Thermostatic Expansion Valve | R407C | External Equalization
Product Description:
The Danfoss TE 2 (068Z3501) is the industry standard for thermostatic expansion valves in small-to-medium refrigeration and air conditioning systems using R407C. In the UAE, where R407C is commonly found in older residential AC units and specialized process chillers, the TE 2 ensures that the evaporator operates at peak efficiency. Its stainless steel power element is laser-welded for maximum durability against the region’s high thermal stress. The valve’s modular design, featuring an interchangeable orifice, allows maintenance teams in Dubai to easily adapt the cooling capacity or perform repairs without replacing the entire valve body, ensuring long-term cost savings and reliability.
Key Features & Benefits:
- Optimized for R407C: Specially charged to provide accurate superheat control for the specific pressure-temperature characteristics of R407C.
- Modular Orifice System: Supports interchangeable orifices (sold separately) for flexible capacity matching in various UAE projects.
- External Equalization: Includes a 1/4 inch flare equalization line to compensate for pressure drops, ensuring precise control in large evaporators.
- High Durability: Laser-welded stainless steel power element provides superior resistance to vibration and corrosion.
- Fast & Stable Response: Quickly adjusts refrigerant flow to prevent compressor damage from liquid floodback, even in high ambient Dubai heat.

FAQs:
- Q: Can I use this R407C valve with R22?
- A: It is not recommended. While pressures are similar, the bulb charge is specific to R407C to ensure the best superheat stability in your UAE installation.
- Q: Does this code include the flare nuts?
- A: Generally, flare nuts are sold separately or come with the tubing; the 068Z3501 is the valve body itself.
- Q: Is it suitable for high-temperature A/C applications in Dubai?
- A: Yes, the TE 2 is excellent for both refrigeration and air conditioning, provided the capacity is correctly matched using the right orifice.
