Small EEV

Hi,

I have an EEV but I do not have enough technical information about it. Also I could not find detailed information about it. It has just this information on it;
1.8C-47 Q12TP01
I have attached a picture of this EEV.
I need to learn type of this EEV, control technics (PWM or uni/bi polar stepper) and also controller type to control this EEV.

Furtherore, Has anybody used Toshiba DA108X1C-20FZ3 (R410A) variable speed compressor.
I need controller for this compressor too.

Thanks,

Does this EEV belong to a particular make of equipment or did you get it as a single item?

edit: OK, found something, but not a lot...
