EEV stepper system (XVD)

EEV stepper system


The driver for the proportional motorised valve XVD is designed to optimize energy efficiency and the refrigerated utilities performance. Its wide compatibility with refrigerants and with the valves on the market, whether unipolar or bipolar, makes this product particularly flexible. In addition, the availability of the service keyboard SKP10 and of the USB interface allows easy and fast set-up of the system.
