Product details
Danfoss TGE Thermostatic Expansion Valve | R22 & R407C | 067N2164
Product Description: The 067N2164 is engineered for systems requiring higher mass flow rates, such as large rooftop units and commercial chillers. In the UAE’s intensive cooling environment, this valve is prized for its balanced port design, which ensures that performance remains consistent even when head pressures spike during the extreme heat of the Dubai summer. The hermetic, all-laser-welded construction eliminates potential leak paths—a vital feature for maintaining system efficiency and complying with UAE environmental standards. With its stainless steel power element and durable brass body, it offers unmatched reliability in high-vibration and high-ambient Middle Eastern installations.
Key Features & Benefits:
- Dual Refrigerant Versatility: Optimized for both R22 and R407C, providing a robust solution for both legacy system maintenance and modern upgrades in the UAE.
- Balanced Port Technology: Guarantees precise flow regulation regardless of condensing pressure variations common in the UAE’s high-ambient climate.
- Leak-Proof Hermetic Build: Laser-welded construction ensures maximum system integrity and reduces refrigerant recharge costs for UAE facility managers.
- Thermal Resilience: Built to maintain accurate calibration and reliable performance in ambient temperatures up to 70°C.
- Bi-metal Solder Connections: Simplifies the installation process for UAE technicians, allowing for direct brazing without the risk of damaging internal components.

FAQs:
- Q: Is the 067N2164 suitable for large-scale chillers in Dubai?
- A: Yes, its high capacity and 1-1/8 inch outlet make it ideal for the medium-to-large evaporators found in UAE commercial complexes.
- Q: Why is the “Balanced Port” design essential for Abu Dhabi summers?
- A: During peak heat, head pressures rise significantly; the balanced port prevents the valve from losing control, ensuring the cooling output remains stable.
- Q: Can I use this for a retrofit from R22 to R407C in the UAE?
- A: Absolutely. It is fully rated for both refrigerants, making it an ideal choice for UAE businesses looking to modernize their cooling systems.
