ETS6-10-18,ETS6-25-32-40,034G5110 Danfoss Electric expansion valves

The range of Electric expansion valves are based
on many years of experience.
ETS 6 secure reliability and provide a precise
solutions for ex pansion and flow control in a
wide range of refrigeration and air conditioning
systems.
Compact and lightweight. The current range is
available with a wide capacity range, and can be
used with all common fluorinated refrigerants.
Bi-flow operation is also possible for heat pump
systems.
The valve operation is by means of a uni-polar
motor, which can be controlled by a number of
controllers from Danfoss or third party vendors.
With an EKD 316 and EIM 336 (current drivers)
and an AKS sensor, an accuracy better than
±  0.5 K can be obtained.
Please contact Danfoss for more details.

 Optimized energy efficiency of the system.
• Precision flow control with high resolution.
• Compact and lightweight.
• Energy saving design.
• Proven know-how and high reliability.
• Wide range for all common refrigerants.
• Bi-flow for heat pump applications.

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.
