Operation Manual
Name plate (main stage)
Parker D*1FE proportional directional control valves
have an integral electronics. Different sizes, as well
as command signal options are available to achieve
an optimal adaption for different applications.
Characteristics of Valve Driver
The described integral electronic driver combines
all necessary functions for the optimal operation of
the valve. The most important features are:
• high dynamic actuator principle with special
designed electronic driver
• closed loop controlled pilot valve and main spool
• Ensured fail-safe behaviour
• constant current actuator control with overcur-
rent shutoff
• excellent properties for response sensitivity and
temperature drift
• differential input stage with various command
signal options
• diagnostic output for spool stroke/overcurrent
state
• standard central connection
• compatible to the relevant European EMC-
standards
