Abstract
A balanced valve system, employing either spool or ball valve members can be pulse width modulated using a solenoid actuator. The solenoid actuator is integrally assembled onto the valve and has a rod by which the solenoid armature imparts a valve operating force to the spool or ball valve member. The rod is press fit into the armature during assembly to establish the desired air gap spacing between armature and pole piece. Movement of the armature causes a corresponding movement in the rod which urges the valve member against compression spring forces to the open or unseated position.
