Design of a new two-dimensional proportional solenoid for miniaturized directional control pneumatic valves

Abstract

In this paper, a new proportional solenoid developed for a miniature 4/3-way directional control valve will be introduced. The new proportional solenoid has two-dimensional structure and a pivoting armature. The most advantageous feature of this solenoid is that its mechanical parts can be easily manufactured and assembled. The working principle and design example of the new proportional solenoid, its application to the activation of a 4/3-way directional valve and the evaluation of its control performance in position control loop will be reported.
