Product details
Danfoss TE 2 Thermostatic Expansion Valve | R404A / R507A | External Equalization
Product Description: The Danfoss TE 2 (068Z3411) is a critical component for maintaining stable cooling performance in low-to-medium temperature applications. In the UAE, where cold chain integrity is vital, this valve provides exceptionally accurate superheat control for R404A and R507A systems. Its external equalization feature allows it to compensate for pressure drops within the evaporator, making it ideal for large supermarket display cases and walk-in freezers in Dubai. The modular design, including an interchangeable orifice, simplifies the service process, allowing technicians to quickly adapt the system’s capacity or perform cleaning without a full valve replacement, ensuring high uptime for critical cooling infrastructure.
Key Features & Benefits:
- Precise Superheat Control: Optimized for R404A/R507A to prevent liquid return and maximize evaporator cooling capacity in UAE heat.
- External Equalization (1/4 in): Essential for systems with distributors or high-pressure drops, ensuring the valve “reads” the evaporator pressure correctly.
- Modular Versatility: Uses interchangeable orifice assemblies (sold separately) for flexible capacity sizing across various Dubai projects.
- Laser-Welded Power Element: Stainless steel construction provides superior strength and resistance to the high-ambient thermal stress of the Middle East.
- Standard Flare Connections: 3/8″ x 1/2″ flare design allows for a straightforward, leak-resistant installation.

FAQs:
- Q: Can I use this valve for R134a?
- A: No, this model is specifically charged for R404A and R507A. Using it with R134a would result in incorrect superheat and poor system performance in your UAE installation.
- Q: Does the 068Z3411 include the orifice?
- A: No, like most TE 2 bodies, the orifice is a separate part that must be sized based on your system’s kW or Tons of refrigeration.
- Q: Is it suitable for high-humidity areas in Dubai?
- A: Yes, the stainless steel power element and robust design are built to resist corrosion in humid and demanding environments.
