A pneumatic slide valve includes a valve housing made of injection-molded plastic material and having a valve bore and a plurality of external ports. The valve housing has an outer housing portion, made of reinforced plastic and determinative for a geometric outer dimension of the valve housing, and an inner housing portion made of non-reinforced plastic and extending continuously in the valve housing. The inner housing portion defines several pressure fluid compartments in fluid communication with the ports and the valve bore at least in a region which is positioned in the area of the pressure fluid compartments, wherein the outer housing portion is molded around the inner housing portion. A slide member is accommodated in the valve bore of the valve housing for displacement in the direction of the axis, for regulating a flow of compressed air between the ports.
