ABSTRACT:
A hydraulic solenoid control valve has the capability of operating at high pulse width modulation frequencies due to precision alignment of the armature and freedom from contamination. An alignment tube coupled at one end to one pole piece aligns coaxially with the armature while a non-magnetic bearing coupled to the other end of the alignment tube also aligns coaxially with the armature. Fluid infusion into the armature cavity is prevented by way of the alignment tube which surrounds the armature.
