A solenoid valve assembly includes an armature having a longitudinal axis and an ovular cross-section, the armature being moveable along the longitudinal axis from a first position to a second position, and a bobbin including a solenoid coil configured to electromagnetically move the armature when energized. The bobbin defines a recess also having an ovular cross section for receiving the armature and restricting lateral movement of the armature, thereby providing a linear actuation path for the armature along the longitudinal axis. A flux coupler and a flux bracket form a magnetic circuit with the bobbin to electromagnetically move the armature. The flux bracket has a pole piece with a commensurate ovular cross-section that limits the movement of the armature along the longitudinal axis, thereby determining a stroke length of the armature. During manufacture, the flux bracket, and therefore the pole piece, are moved relative to the flux coupler to set the stroke length.
