Product Description
Danfoss Types ETS6-10/ETS6-18-25/ETS32-40 Electric expansion valves introduction
The range of Electric expansion valves are basedon 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 Danfoss Types ETS6-10/ETS6-18-25/ETS32-40 Electric expansion valves Features
• 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.
Danfoss Types ETS6-10/ETS6-18-25/ETS32-40 Electric expansion valves Technical data
Flow characteristic Bi-flow.
Maximum working pressure 47 bar / 681 psig.
Compatible refrigerants R134a, R404A, R407C, R410A, R22 and other refrigerant.
Refrigerant oil All mineral oils and ester oils (to lubricate ETS 6 valve).
Ambient temperature -30 – 70°C / -22 – 158 °F
Fluid Temperature
(measured at the inlet of the
valve like the image below)
-30 – 70°C / -22 – 158 °F
Durability
Tested for 60 Million total pulses supplies to the valve during partially open
valve, which is comparable to 150,000 cycles if the valve is operated between
100 to 300 pulses open.
Tested for 30,000 full stroke cycles including 20 pulse overdrive at each closing.
Ambient humidity 95 % RH or less.
Capacity control range 10 % – 100 %
Electrical data
Modulation Permanent magnet type direct operating stepper motor.
Excitation method 1-2 phase.
Electrical connection JST XHP-6, JST XHP-5 and AMP connection.
Excitation speed min. 30 pps (pulses per second) to max. 90 pps, recommended 31 pps.
Operating range
0 to 480 pulses, no holding power required (NOTE: do not apply more than
520 pulses).
Full motion transit time e.g. 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
Compatible Danfoss controller EKD 316, EKD 316C, EXD 316, EIM 336 (for OEM only).
Danfoss Types ETS6-10/ETS6-18-25/ETS32-40 Electric expansion valves 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 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.
