An electronic expansion valve is a device precisely regulating the amount of refrigerant entering the condenser. You will learn here what you need about EEVs.
The Danfoss series of electric expansion valves called ETS, can offer you efficient and reliable operation, covering any air conditioning system requirements.

Sporlan SEH(I) Electric Expansion Valves are electronically controlled, stepper motor driven valves, intended for precise control of liquid refrigerant flow. Featuring high resolution actuator assemblies, these valves provide unmatched control capability across a wide range of applications and loads.
The resolution of an Electric Expansion Valve (EEV) is governed by the stroke and number of steps in that stroke. Sporlan offers nine standard Electric Expansion Valves to cover the full nominal capacity range from 2.5 to 434 tons (8.2 to 1424 kW) using R-22. All valves currently offer 2500 steps of stroke, except for the two
Parker-Sporlan’s SER(I) valves are stepper motor actuated electric expansion valves intended for use in direct expansion refrigeration and air conditioning applications. The SER valve is suited for a wide range of applications due to its compatibility with HCFC, HFC, HFO and HC refrigerants and Mineral, Alkylbenzene and Polyolester Oils.

The electronic expansion valve (EEV) operates with a much more sophisticated design. EEVs control the flow of refrigerant entering a direct expansion evaporator. They do this in response to signals sent to them by an electronic controller. A small motor is used to open and close the valve port. The motor is called a step or stepper motor.

Electronic expansion valves are an evolution on the thermal expansion valve. They are much more sophisticated and allow the refrigeration system to operate much more accurately and efficiently. You’ll usually see electronic expansion valves listed with the acronym of either EEV or EXV.
