A proportional solenoid-driven valve control assembly contains a moveable, magnetic armature (170) positioned adjacent to one end (222) of a fixed pole piece (224) that protrudes from a solenoid bore (245) and is supported by means of a compact suspension spring arrangement (190, 191) adjacent to the one end of the bore (245). The movable armature (170) is configured to provi de two radial magnetic flux paths. One flux path traverses a fixed radial shunt gap (177) at one end (222) of the fixed magnetic pole piece (224) that is located in and protrudes from the one end of the solenoid bore (245). The other flux path traverses a variable geometry reluctance gap (236) defined between a radially projecting, tapered rim portion (174) of the armature (17 0) and an inwardly projecting tapered portion (231) of the solenoid assembly housing (230).
