A vacuum valve comprising valve housing (1), a continuous line (3) in the valve housing (1) the conductance of which is to be set; a movably supported valve body (5) extending into the line (3) and having a position (H) which defines a conductance through line (3). A setting device (11) is connected to the valve body (5) and having a setting displacement. Locally offset snap-in devices (22; 29, 30) along this setting displacement and effective for snap receiving the setting device (11) for setting displacement positions, the snapping-in at each of the snap-in devices (22; 29, 30) being releasable again by increasing a driving force acting on the setting device (11).
