Danfoss TGE Thermostatic Expansion Valve | R410A | 067N3158
Product Description: The 067N3158 is engineered to withstand the high-pressure demands of R410A refrigeration and air conditioning. In the UAE’s intensive cooling market, this valve is a staple for rooftop units, chillers, and close-control systems in Dubai and Abu Dhabi. It features a balanced port design, which is essential for maintaining stable performance even when condensing pressures fluctuate due to the extreme Middle Eastern summer heat. The hermetic, all-laser-welded construction eliminates common leak paths, ensuring that the system remains charge-consistent and environmentally compliant. With its stainless steel power element and bi-metal connections, it offers a durable and easy-to-install solution for UAE mechanical contractors.
Key Features & Benefits:
- R410A High-Pressure Ready: Specifically calibrated for the thermophysical properties of R410A, the standard for modern UAE commercial cooling.
- Balanced Port Performance: Ensures consistent refrigerant flow regardless of changes in head pressure caused by high ambient temperatures in the UAE.
- Hermetic, Leak-Proof Design: All-welded construction provides maximum security against refrigerant loss in high-vibration UAE industrial environments.
- Corrosion Resistance: Features a stainless steel power element and capillary tube to withstand the humid and saline air of coastal Dubai.
- Bi-metal Solder Connections: Simplifies the brazing process, allowing for direct installation without the risk of internal valve damage.
