丹佛斯ETS6-25-32,ETS6-40,034G5065系列电子膨胀阀的设计参数

设计参数：

ƒ

Maximum working pressure 47 bar (667 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°C to 70°C (-22 °F to 158° F)

Fluid Temperature -30°C to 70°C (-22 °F to 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

Modulation Permanent magnet type direct operating stepper motor

Excitation method 1-2 phase

Electrical connection JST XHP-6 and JST XHP-5

Excitation speed min. 30 pps (pulses per second) to max. 90 pps, recommended 31.3 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)

丹佛斯ETS6-25-32,ETS6-40,034G5065系列电子膨胀阀的基本原理

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 **s are applied to the

surrounding coil.

Within the coil structure, there are different

winding configurations, and the polarities are

changed by the electrical **s applied. By

application of the appropriate combination of

**s, 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.
