Danfoss 067N4167 TGEZ 30,0 R407C Fixed Orifice

To precisely control the refrigerant flowing to the evaporator in refrigeration systems, the Danfoss 067N4167 TGEZ 30,0 R407C Thermostatic Expansion Valve increases system efficiency and stability with its interchangeable orifice design that provides balanced superheat control. Its element and sensing bulb design compatible with R407C refrigerant gas delivers reliable performance in commercial refrigeration and air conditioning applications.

Precise Superheat Control and High System Efficiency

The thermostatic expansion valve continuously measures the superheat value at the evaporator outlet and automatically adjusts the refrigerant flow rate, thus protecting the compressor against liquid flood-back. The stainless steel sensing element (bulb), connected to the element head by a capillary tube, responds quickly to temperature changes in the evaporator line and ensures stable operation even under variable loads. Thanks to the interchangeable orifice principle, the valve body can be easily adapted to different capacity requirements.
