Abstract: Described herein is a system for controlling a solenoid valve, which includes a driving circuit for driving a solenoid of the solenoid valve and a control unit for controlling the driving circuit. The control unit is configured for generating in the solenoid, during operation of the solenoid valve: first current signal for moving the open/close element from a first position to a second position, which is generated by the external supply network, to which the solenoid is connected; and second current signal, which is generated exclusively as a result of residual magnetism in the magnetic element of the solenoid valve and is activated when the open/close element is still in the aforesaid second position.
