Electric expansion valves
Type ETS 6
The range of Electric expansion valves are based on many years of experience.
ETS 6 secure reliability and provide a precise solutions for expansion 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 EKE 1V 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.

Design/function |
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 |
Needle valve
Valve body
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.

Valve Selection |
For optimum performance, it is important to |
When selecting the valve it may be necessary to |
correct the evaporator capacity. In order to |
apply a correction factor to the actual evaporator |
|
|
select the correct size of ETS 6 you will need the |
capacity. This correction factor is required when |
|
following information: |
system conditions are different than table |
|
|
conditions. Selection also depends on having an |
|
Refrigerant: HCFC / HFC |
acceptable pressure drop across the valve. In the |
|
Evaporator capacity Qe in kW or TR |
selection table, the pressure drop in the liquid |
|
Evaporating temperature te in °C / °F |
line is assumed to be zero. The following example |
|
Condenser temperature tc in °C / °F |
illustrates correct selection of the valve. |
|
Subcooling Δtsub in K / °F |
Refrigerant: R407C |
|
|
|
|
|
Evaporator capacity: Qe = 10 kW / 2.84 TR |
|
|
Condensing temperature: tc = 40 °C / 104 °F |
|
|
Evaporating temperature: te = +10 °C / 50 °F |
|
|
Subcooling Δtsub = 10 K / 18 °F |
Note!
Coolselector®2 is a Danfoss calculation and selection software designed to make selection processes for all refrigeration projects easier and less time consuming. For details refer http://coolselector.danfoss.com

Valve Selection
(continued)
Step 1
Determine the correction factor for subcooling Δtsub. From the correction factor table (see below) a subcooling of 10 K, R407C corresponds to a factor of 1.14.

Step 2
Corrected evaporator capacity is
Qe (Corrected) = 10 kW /1.14 = 8.8 kW / 2.5 TR
Step 3
Select the appropriate capacity table, R407C, and choose the column for condensing temperature of tc = 40°C / 104 °F and evaporating temperature of te = 10°C / 50 °F which will provide an equivalent or greater capacity of 8.8 kW / 2.5 TR. ETS 6 - 18 provides 10.35 kW / 2.94 TR, which is the proper selection for this example.
Step 4
Choose ETS 6 -18:
•• Single pack code no. 034G5026
•• I-pack code no. 034G5024
