Thermostatic expansion valve
Type TD 1 / TDE 1
Version 2
TD 1 / TDE 1 is a thermostatic expansion valve designed to regulate refrigerant injection into evaporators. The injection depends on the refrigerant superheat at the evaporator outlet, where the bulb must be placed.
TD 1 / TDE 1 is constructed for hermetic sealed systems and supplied as angleway and straightway version.
OEM Applications:
• GDM (Glass Door Merchandiser)
• Commercial fridge and freezer
• Heat Pump

TD 1 / TDE 1 valves have a •xed ori•ce assembly. Both straight way and angle way con•guration are available and the angle way version is designed with •xed superheat setting only.
The valves are available with internal or external pressure equalization. External pressure equalization should always be used on systems with liquid distributors.
The stainless steel capillary tube and bulb with Danfoss patent bulb strap give reliable connection. It gives fast and precise reaction to temperature changes in the evaporator.
