Abstract
A solenoid valve device that includes a solenoid valve; a drive circuit that drives the solenoid section; a current sensor that detects a current applied to the solenoid section; and a control unit that controls, when the solenoid valve is served as the pressure control valve, the drive circuit by performing a feedback control based on the current detected by the current sensor so that a current in accordance with an output pressure command is applied to the solenoid section, and controls, when the solenoid valve is served as the solenoid pump, the drive circuit without performing the feedback control so that a pump current is applied to the solenoid section.
