A solenoid-operated valve device is provided which includes a valve, a solenoid actuator designed to be supplied with electric power from a battery to operate on voltage substantially identical with that outputted from the battery to move the valve, and a controller working to energize said solenoid actuator. Prior to entering a main energization mode to energize the solenoid actuator to open or close the valve, the controller works to supply a low current to the solenoid actuator to create magnetic field therein to assist in energizing the solenoid actuator in the main energization mode quickly at a high speed. The controller may alternatively be designed to step-up the voltage to be applied to the solenoid actuator initially prior to entering the main energization mode.
