The solenoid portion includes a solenoid housing defining a solenoid interior, a coil, and an armature, with the armature being moveable along the longitudinal axis in response to energization of the coil. The solenoid-actuated valve also includes a valve portion coupled to the solenoid portion. The valve portion includes a valve member moveable by the armature. The solenoid-actuated valve further includes a valve filter disposed in the solenoid interior and/or coupled to the solenoid housing and configured to separate the solenoid interior from a hydraulic circuit when the valve portion is coupled to a valve housing for allowing fluid to flow into and out of the solenoid interior upon actuation of the armature. ## Claims ### Claim 1 A solenoid-actuated valve comprising: a solenoid portion extending along a longitudinal axis, with said solenoid portion comprising, a solenoid housing disposed about said longitudinal axis and defining a solenoid interior, a coil disposed about said longitudinal axis and in said solenoid interior, and an armature disposed about said longitudinal axis and in said solenoid interior and between said longitudinal axis and said coil, with said armature being moveable along said longitudinal axis in response to energization of said coil;
