The invention relates to an electrohydraulic brake slip control device for motor vehicles, including one or more electromagnetically actuatable hydraulic valves contained in a valve block, having valve domes, which protrude at least partway beyond the valve block in the direction of a valve axis and each engage in a coil opening of an electric coil held by a coil holder, and having contact elements, which protrude away from the coils and through openings of a top plate, in order to electrically activate the coils. At least some of the coils are held against the coil holder in a plane perpendicular to the valve axes with an easily moving play, but also in a position-oriented fashion and, after their alignment produced by the engagement of the valve domes in the associated coil openings, can be rigidly fixed in the aligned position.
