Abstract
A coil assembly comprises a bobbin for supporting a coil. The bobbin supports a metal ferrule. A metal bracket is releasably coupled to the bobbin. The bracket holds the ferrule in place. The ferrule and the bracket are arranged to cooperatively serve as a return path for magnetic flux. A method for assembling a solenoid valve may comprise the steps of coupling a flux return structure about a coil, connecting the coil to an electrical circuit, and orienting the coil about the armature of the valve.
