Abstract: The invention relates to a slide valve, especially for controlling a flow of catalyst or like high-temperature media, having a pipe portion (10) and, arranged therein, a restrictor (11) which has an inlet opening and an outlet opening (12a, 12b) through which flow takes place during operation, and having a slide plate (13) which co-operates with the outlet opening (12b) to control the flow of catalyst and which is movable into an open position and a closed position I, II, the slide plate (13) being mounted so as to be displaceable by means of guide elements (14, 15) arranged on the pipe and on the plate, which guide elements are in engagement with one another. The invention is distinguished by the fact that the pipe-associated guide elements (14) are arranged before the outlet opening (12b) in the direction of flow.
