Abstract
A method for controlling or regulating a vacuum valve that includes: a valve body () with a valve opening (); a closing member () that can be moved between an open position and a closed position over a closing path (s) for closing the vacuum valve and that closes the valve opening () in the closed position, in which at least one elastic seal () is pressed onto a seal face (); an actuator () for moving the closing member (); and a control device () by which the actuator () can be triggered; the point (p) of the closing path (s) at which the elastic seal () contacts the seal face () and/or a velocity (v) of the closing member () at that point is used as a controlling parameter for the control device ().
