Product details
Danfoss TGE Thermostatic Expansion Valve | R22 & R407C | 067N2161
Product Description: The 067N2161 is a medium-capacity valve ideal for commercial units such as rooftop ACs and small-to-medium water chillers. In the UAE’s demanding climate, where equipment must handle intense thermal loads, this valve’s balanced port design is essential. It ensures that the valve’s performance remains consistent despite the high and fluctuating condensing pressures typical of Dubai summers. Its hermetic, all-laser-welded construction eliminates potential leak paths, providing a maintenance-free solution for critical infrastructure. The high-grade stainless steel power element ensures durability and protection against the corrosive coastal air of the Middle East.
Key Features & Benefits:
- Dual Refrigerant Compatibility: Optimized for both R22 (for maintaining existing UAE systems) and R407C (for modern installations).
- Balanced Port Technology: Guarantees stable and precise superheat control despite the wide fluctuations in head pressure found in the UAE.
- 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 components.

FAQs:
- Q: Is the 067N2161 suitable for commercial AC units in Dubai?
- A: Yes, the 5/8″ x 5/8″ connection size is a standard for many medium-sized commercial evaporators and rooftop units used across the UAE.
- Q: Why is the “Balanced Port” important for Sharjah installations?
- A: It prevents the valve from “hunting” (unstable operation) when the outdoor temperature varies, ensuring the system provides consistent cooling to the building.
- Q: Does this valve require regular maintenance?
- A: No. 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.
