3.3 Description of operating principle
The current that fl ows through the coil winding creates a magnetic fi eld. The
magnetic fi eld acts on the solenoid armature and causes it to move, thereby moving
the valve control element (spool, sealing element).
The coil is accommodated in a steel housing, thus amplifying the magnetic fi eld and
protecting the device against mechanical damage.
In addition, the coil is embedded in plastic material to mould it into the housing.
Also the part of the connector coupled to the coil is made of the same plastic
material. A silicone seal protects the coil space from the ingress of moisture and
dust.
