Abstract
Abstract A motor operated valve unit including a fluid valve driven by an electric motor through a suitable drive mechanism, and a heat dissipating clip member comprised of a horizontal gripping portion and a pair of depending flange portions formed integrally therewith. The gripping portion is provided with a circular gripping edge which extends slightly over 180° from tip to tip. The clip member is snapped into a groove on the electric motor and is dimensioned so that the flanges thereon will be in snug contact with the inside surface of a removable cover member.
