A valve is provided having a solenoid coil in an integrally formed magnetic material having a cross-sectional configuration resembling a bundt pan. Such a structure can be stamp-formed and creates an enlarged surface area available for the magnetic flux to the armature at the bottom of the bundt cross-section. However, since the ends of the stamped structure are not relevant to the magnetic circuit, they can be left unfinished. A thin, flat plate armature and an axial flow valve assembly allows for low friction, low mass movement of the valve seal. Placement of the armature and solenoid across a small air gap provides a high force, very fast response time with minimal electrical power consumption.
