Method for adjusting the throttling action of a valve comprising a valve body with at least one through-channel for a working medium, where the working medium is throttled by at least one valve disk which covers the throttle channel. By making use of the effect of the heat of a laser beam to change the elastic pretension of the disk, deviations from a predetermined throttling action are minimized. The laser beam is used to cause partial local melting in the minimum of one valve disk, the heat thus introduced having the effect of working at least one defined bending axis into the disk.
