Stroke-Controlled Proportional Solenoid

In the case ol the stroke-controlled solenoid (Fig 10). the position of the armature is controlled by a ciosed-loop control circuit and maintained irrespective of the counter-pressure. provided it is within the rated working range of the solenoid. With the stroke-controlled solenoid, the spools of proportional directional, flow as well as pressure control valves can …

Force-controlled Proportional Solenoid

The solenoid force is controlled by the change in current I in the lorce-controlled solenoid without the armature of the solenoid performing a measurable stroke. Due to current feedback in the electrical amplifier, the solenoid current and therefore the solenoid force are kept constant even if resistance changes. The main feature of the force-controlled proportional …
