A vehicular anti-lock brake system control unit having a control valve includes a housing with a control valve bore therein. The control valve includes a sleeve with a moveable armature, and a coil surrounding the sleeve for moving the armature. The control valve also includes a valve body having an outer end attached to the sleeve and an inner end seated within the control valve bore of the housing. The valve body has an outer diameter no greater than the outer diameter of the coil such that minimum spacing between multiple control valves in the control unit is not limited by the outer diameter of the valve body, a construction which is facilitated by constructing the flux ring as a component separate from the valve housing and, in one form, adapted to be a part of the coil assembly carried by a separate electric control module.
