Abstract
A method for controlling or regulating a vacuum valve that includes: a valve body (1) with a valve opening (2); a closing member (3) 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 (2) in the closed position, in which at least one elastic seal (4) is pressed onto a seal face (35); an actuator (5) for moving the closing member (3); and a control device (9) by which the actuator (5) can be triggered; the point (p) of the closing path (s) at which the elastic seal (4) contacts the seal face (35) and/or a velocity (v) of the closing member (3) at that point is used as a controlling parameter for the control device (9).

Method for controlling or regulating a vacuum valve that comprises:
- 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 for closing the vacuum valve and that closes the valve opening in the closed position, wherein, in the closed position, at least one elastic seal is pressed onto a seal face and, during movement of the closing member from the open position into the closed position, the elastic seal first comes into contact with the seal face at a contact point of the closing path,
- an actuator for moving the closing member, and
- a control device by which the actuator is triggered,
- wherein the velocity of the closing member at the contact point is used as a controlling parameter for the control device when the control device controls the moving of the closing member from the open position to the closed position.
