Product details
Danfoss TGE Thermostatic Expansion Valve | R410A & R32 | 067N3159
Product Description: The TGE series is designed for demanding air conditioning and chiller applications. In the UAE’s intensive cooling market, the 067N3159 stands out for its robust hermetic construction, which eliminates potential leak paths, making it ideal for the high operating pressures of R410A and R32. This model features a balanced port design, which ensures that changes in head pressure (common during the extreme UAE summer) do not affect the valve’s opening performance. Whether used in rooftop units, VRF systems, or water chillers in Dubai and Abu Dhabi, the 067N3159 provides precise superheat control and exceptional reliability under heavy thermal loads.
Key Features & Benefits:
- R410A & R32 Ready: Fully optimized for high-pressure, modern refrigerants used in the UAE’s latest energy-efficient HVAC projects.
- Balanced Port Design: Provides stable performance across a wide range of ambient temperatures, crucial for Dubai’s varying day/night cooling loads.
- Hermetic Construction: All-laser-welded stainless steel and copper design significantly reduces the risk of refrigerant leaks.
- High-Pressure Reliability: Engineered to withstand the rigorous demands of UAE commercial cooling without loss of calibration.
- Bi-metal Connections: Facilitates easier and safer brazing during installation in UAE mechanical rooms.

FAQs:
- Q: Can I use the 067N3159 with R32 systems in the UAE?
- A: Yes, this TGE model is specifically rated for both R410A and the flammable A2L refrigerant R32, making it a future-proof choice for UAE installations.
- Q: Why is the “Balanced Port” feature important for Dubai?
- A: It prevents the valve from overfeeding or starving the evaporator when the condenser pressure fluctuates due to high outdoor temperatures.
- Q: Is this valve suitable for heat pump applications?
- A: Yes, the TGE series is designed to handle bi-flow or high-load conditions often found in UAE heat pump and chiller systems.
