Working Principle
The armature is attracted to the core by an electromagnetic force as the coil is energised.
When the applied current varies, the attraction force also varies proportionally to it.
The flow rate is controlled by the movement (stroke) of the armature, depending on the
balance between the attraction force and the spring load.
Flow rate can be controlled smoothly with one proportional
solenoid valve by current control.

One 2-port valve is required for
each flow rate.
