Product details
Danfoss TGE Thermostatic Expansion Valve | R22 & R407C | 067N2157
Product Description: The 067N2157 is built for high-mass flow applications, featuring a large 1-1/8 inch outlet connection. In the UAE’s intensive cooling sector—where large-tonnage water chillers and massive rooftop units are the standard—this valve provides unmatched reliability. Its balanced port design is a critical feature, ensuring that the valve maintains stable superheat control even when head pressures fluctuate significantly due to the peak Dubai summer heat. The hermetic, laser-welded construction ensures a leak-proof operation, reducing maintenance overhead and protecting the system’s refrigerant charge in high-vibration industrial environments.
Key Features & Benefits:
- Industrial-Grade Capacity: Optimized for high-tonnage cooling loads in UAE commercial complexes and industrial refrigeration plants.
- Balanced Port Technology: Guarantees precise flow regulation regardless of condensing pressure variations common in the Middle Eastern climate.
- Hermetic, Leak-Proof Design: The all-welded stainless steel and copper build eliminates potential leak paths, ensuring maximum system security in Abu Dhabi.
- Dual Refrigerant Versatility: Fully rated for both R22 and R407C, providing a robust solution for both legacy system maintenance and modern upgrades in the UAE.
- Thermal Resilience: Specifically designed to maintain accurate calibration and reliable performance in ambient temperatures up to 70°C.

FAQs:
- Q: Why is the 067N2157 preferred for UAE industrial chillers?
- A: Its combination of high flow capacity and a balanced port allows it to handle large evaporators while remaining stable during the extreme outdoor temperature shifts of the UAE.
- Q: Can this valve handle the high humidity of coastal regions?
- A: Yes, the stainless steel power element and hermetic design are highly resistant to corrosion from humid and saline air in coastal Dubai and Sharjah.
- Q: Does this valve require a specific orientation for installation?
- A: While it can be installed in most positions, it is recommended to follow the flow arrow on the valve body and ensure the sensing bulb is properly insulated for accurate readings in the UAE heat.
