An electrically operated drain valve for recreational vehicles economically fabricated primarily of synthetic plastic parts which is relatively free of corrosion at critical areas and readily retrofitted to existing recreational vehicle drain systems. A housing containing a geared reversible electric motor operating a linear displaceable rack associated with the drain valve operator permits the drain valve to be displaced between open and closed positions.
