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. To mitigate disruptions by coating material which has made its way into a bearing gap between the valve bore and the bearing faces at least one receiving space is incorporated in an inner circumferential face of the valve bore between the supply duct and the nozzle duct.
