Abstract: A solenoid valve system is described which has a solenoid valve and a base operatively connected to the solenoid valve. Each solenoid valve has a compressed air supply conduit, a compressed air delivery conduit, air discharge conduit, air distribution box, configured so as to selectively put in fluid connection the conduits of the solenoid valve, and an electropilot, configured for activating the air distribution box. Each base has a plurality of housings each able to receive a single solenoid valve. Each housing is internally provided with air passage conduits that are put in fluid connection with the conduits of the solenoid valve fixed on the housing. Each base is selected from a group consisting of a base with three housings and a base with four housings.
