Estimating the term…
A valve includes a spring having a spring force, an actuator having an actuator force that acts against the spring force, and a tappet that can be actuated by means of the actuator. The valve also includes a sealing element, which is or can be coupled to the tappet, and a sealing seat, such that the valve is closed when the sealing element lies against the sealing seat. A current having a specified curve, proceeding from an initial value of the current to a specified final value of the current, is applied during a specified time interval of the actuator after a closing phase of the valve for a normally open valve or after an opening phase for a normally closed valve. The initial value of the current is less than the final value.
A method for controlling a valve that comprises a spring having a spring force, an actuator having an actuator force acting against the spring force, and a tappet which can be actuated by means of the actuator, a sealing element, which is or can be coupled to the tappet, and a sealing seat, such that the valve is closed when the sealing element bears on the sealing seat, the method comprising:
