Valves designed for a change of fluid direction, such as directional control valves and  poppet-type valves, are often solenoid operated. Proportional valves are another large  group controlling continuously parameters in the circuit within the defined interval.  Electric current flowing through the coil winding creates a magnetic field. This field acts on  the armature of the solenoid part and allows its shift which is then transferred to the  valve control element (spool, poppet). The excitation winding made of copper wire placed  on a plastic core is the basis. The coil is inserted into the steel housing amplifying the  magnetic field and to protect it against mechanical damage. Moreover, the coil is molded  into the housing by plastic material. The connector part coupled with the coil is also made  of the same plastic. A silicone seal protects the coil space against moisture and  dust.
