Abstract
A switchable slot valve for a coating plant controls delivery of a pasty coating material. The switchable slot valve has a valve bore incorporated in a valve main body and is aligned in a valve extent direction, and a valve control rod is rotatable to switch between a throughput position and a closed position and is mounted in the valve bore by bearing faces is disposed. To mitigate disruptions by coating material which has made its way into a bearing gap between the valve bore and the bearing faces, depression regions are provided in the region of which the respective outer circumferential part-face does not bear on the inner circumferential face of the valve bore, on the outer circumferential part-faces between the slot-shaped duct inlet and the slot-shaped duct outlet.
