A hydraulic assembly for slip-controlled brake systems of motor vehicles, having a valve block with receiving bores, each for a hydraulic part of electromagnetically actuated valves, each of which contains magnetically active elements and a respective electric part having an electric coil encompassing the valve dome, a coil housing, and a washer that is contained at least indirectly in the coil housing, on the side oriented toward the hydraulic part. The washers of at least some of the valves are interconnected to form a multi-washer component. The production of the hydraulic assembly then includes the production of a structural unit, which supports the respective electric parts of at least some of the valves, by connecting the coil housing to the associated washers of the multi-washer component, and the placement of this structural unit onto the valve block by introducing the valve domes into through openings of the washers.
