The present invention relates to a method and a circuit system for operating a solenoid valve (MV), particularly for actuating an electrohydraulic gas-exchange valve control, an injection valve, or an intake or exhaust valve of an internal combustion engine. To permit the simplest possible driving of the solenoid valve (MV), it is proposed that the solenoid valve (MV) be acted upon in a controlled manner in a cycle including three phases, in which in a pull-up phase, the solenoid valve (MV) is connected for a predefined time duration (T-1) to a first voltage (U-1) of predetermined magnitude for generating a pull-up current, in a holding phase is connected to a second voltage (U-2) of predetermined magnitude for generating a holding current, and in a de-energize phase is separated from both voltages (U-1, U-2).
