| description | A method and a valve arrangement are provided for electronic wear state determination of the valve arrangement for controlling a process medium flow. A valve element, which is arranged so as to move axially within a valve housing, is moved via electrically drivable linear drive means on the basis of positioning regulation. The valve element has an essentially constant drive force applied to it, and a position speed profile over the switching travel of the valve element is determined by detecting the speed as a function of the current position of the valve element. A change profile is created by comparing the determined speed profile with previous position speed profiles, as a measure of the position-dependent wear state of the valve mechanism. |
