Product details
Danfoss TGE Thermostatic Expansion Valve | R22 & R407C | 067N2031
Product Description: The 067N2031 is a compact yet powerful valve ideal for small to medium-sized commercial units. In the UAE’s demanding climate, where equipment must handle high thermal loads, this valve’s balanced port design is essential. It ensures that the valve’s performance remains consistent despite the high condensing pressures typical of Dubai summers. Its hermetic, all-laser-welded construction eliminates potential leak paths, providing a maintenance-free solution for rooftop units and split systems. The stainless steel power element ensures durability and protection against the corrosive coastal environments of the Middle East.
Key Features & Benefits:
- Dual Refrigerant Compatibility: Optimized for both R22 (legacy maintenance) and R407C (modern installations) in the UAE.
- Balanced Port Technology: Guarantees stable and precise superheat control despite the wide fluctuations in head pressure found in the Middle East.
- Leak-Proof Hermetic Build: Laser-welded construction ensures maximum system integrity and eliminates the need for gaskets in UAE facilities.
- High-Ambient Reliability: Specifically built to maintain accurate calibration and performance in temperatures up to 70°C.
- Bi-metal Solder Connections: Simplifies the brazing process for UAE technicians, allowing for a secure installation without risking damage to internal parts.

FAQs:
- Q: Is the 067N2031 suitable for small commercial AC units in Dubai?
- A: Yes, the 3/8″ x 1/2″ connection size is perfect for light commercial evaporators and high-efficiency split units used across the UAE.
- Q: Why is the “Balanced Port” important for Sharjah installations?
- A: It prevents the valve from “hunting” or becoming unstable when outdoor temperatures vary, ensuring the system provides consistent cooling to the building.
- Q: Does this valve require regular maintenance?
- A: Due to its hermetic, all-welded design, this valve is essentially maintenance-free. If it fails, the entire unit is replaced to ensure a leak-proof system.
