Operating range
0 to 480 pulses, no holding power required (NOTE: do not apply more than
520 pulses)
Full motion transit time 16 sec @ 30 pps, 6 sec @ 80 pps
Installation position
Liquid line solenoid valve
With coil on the upper side and the valve/coil assembly within ±15?of the
vertical axis
If using a liquid line solenoid valve, it must be installed in such a way that it
does not create liquid hammering this ETS 6 valve
Max. coil winding temperature 115 °C (239 ° F)
基本原理：
The ETS 6 electronic 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.
