The invention relates to a method and to a device for controlling a valve, which valve comprises a spring, an actuator and a pin that can be actuated by means of the actuator. A current having a specified course is applied to the actuator, starting from an initial value of the current at which the pin is in an initial position, in which the pin allows for a normally open valve to close and allows for a normally closed valve to open. The course of the current is specified in such a way that said course has a section or several consecutive sections, wherein each of the sections has respectively an initial value and a final value of the current, a first time interval having a continuously falling current course, and a second time interval following the first time interval having a continuously rising current course. The sections are designed in such a way that after the respective section has been passed through, the final value of the current is less than the initial value of the current. After the specified course of the current has been passed through, the pin is in a final position, in which the pin does not allow for a normally open valve to close and does not allow for a normally closed valve to open. |
