Solenoid-actuated control valves having low hysteresis include an annular flux housing with an axial bore extending therethrough. A coil configured to generate a magnetic field is disposed within the flux housing. A magnetic pole piece is disposed within the flux housing axial bore. A magnetic armature is slidably secured within the flux housing axial bore. A spring, positioned between the pole piece and armature, is configured to urge the armature away from the pole piece. A spool valve, slidably secured within a spool sleeve, is mechanically coupled with the armature such that the spool valve follows movement of the armature as a slave.
