Abstract
A shut-off slide valve for use in pipelines or for closing a container aperture includes a housing, a shut-off member formed of a sealing plate and a counter element spaced from the sealing plate and displaceable in the housing, and an actuation member for displacing the shut-off member in the housing, with the actuation member having a portion extending between the sealing plate and the counter element, and at least one of the sealing plate and the counter element having a collar substantially bridging the space between the sealing plate and the counter element, so that the shut-off member has a shape similar to that of a lid-covered can.
