A circuit for driving a solenoid valve having a valve which is driven by an exciting current flowing through a solenoid coil to open/close the solenoid valve comprises at least one ON-OFF switch which operates in response to the movement of the valve, and a stand-by exciting current to intermittently energize the solenoid coil is supplied whereby the valve is oscillated at a position just before starting to open or close the solenoid valve. The oscillating state of the valve reduces the static frictional force that would otherwise act on the valve can be eliminated and the high speed operation of the solenoid valve can be realized.
