Danfoss TGE Thermostatic Expansion Valve | R22 & R407C | 067N2305

Product Description: The 067N2305 is a heavy-duty expansion valve designed for maximum flow and reliability. In the UAE’s challenging climate, this valve is primarily used in large water chillers, industrial refrigeration plants, and central air conditioning systems in Dubai and Abu Dhabi. Its balanced port design is essential for Middle Eastern operations, ensuring that the valve remains stable even when outdoor temperatures cause significant fluctuations in head pressure. The hermetic, all-laser-welded stainless steel and copper construction provide the ultimate protection against refrigerant leaks, which is vital for maintaining system efficiency and complying with UAE environmental standards for large-scale cooling infrastructure.

Key Features & Benefits:

• Maximum Flow Capacity: Designed for the highest cooling loads in UAE industrial evaporators and large-tonnage commercial chillers.
• Balanced Port Technology: Guarantees precise superheat control and stable operation despite the extreme condensing pressure variations common in the UAE summer.
• Leak-Proof Hermetic Build: Laser-welded construction eliminates gaskets and mechanical joints, ensuring a maintenance-free, leak-proof life in high-vibration environments.
• Dual-Refrigerant Support: Optimized for both R22 and R407C, providing a versatile solution for UAE facility managers upgrading or maintaining large systems.
• Corrosion & Thermal Resistance: High-grade materials ensure the valve maintains calibration in high-ambient temperatures and humid coastal conditions.
