1 Description
The slip-on coils can be replaced without opening the hy
draulic envelope and can be positioned at any angle
through 360°. When combined with the appropriate core
tube, the coils produce an on/off solenoid function or a pro
portional solenoid function. Thanks to the wide variety of
connector types and voltages, these coils are suitable for
widespread use in mobile and industrial applications. These
coils are very adaptable in use, a benefit that is enhanced
by various power ratings. The plug base are plastic. The
body is zinc-nickel plated according to DIN 50979 and is
thus suitable for use in the harshest operating environ
ments.

5 Installation information
Attention.
Because of the danger of overheating, the coil
must only be operated when it is properly fitted on
a valve.
Attention.
Delivery is done without mating connector.
