ETS 6-25 5/16" ODF Electric Expansion Valve

The ETS 6 Electric expansion valves open and close to regulate refrigerant flow by means of a screw, whose rotating motion is transformed into linear motion. This occurs by the rotation of a magnet-needle valve assembly which moves when electrical signals are applied to the surrounding coil.
Within the coil structure, there are different winding configurations, and the polarities are changed by the electrical signals applied. By application of the appropriate combination of signals, in the form of pulses, the coil forces the rotor of the valve to move in a stepwise fashion.
Application of multiple pulses will make the valve mechanism to move through a series of steps in the chosen direction, in order to set the valve with the required opening degree.
