Abstract: An injector for injecting a reagent includes an axially translatable valve member positioned within a housing. An electromagnet is positioned within the housing and includes a cylindrically-shaped coil of wire. The valve member moves between a seated position and an unseated position in response to energizing the electromagnet. A flux sleeve passes through the coil and includes two magnetic portions interconnected by a flux bridge portion or a flux break portion. Each of the magnetic portions is aligned with transverse planes defined by the ends of the cylindrical coil. The flux bridge portion or flux break portion is axially positioned between the transverse planes.
