Characteristics of valve driver
The integral electronic driver combines all func-
tions for optimal operation of the valve. Thanks
to its excellent dynamics, the valve is deployable
within closed loop control applications. The most
important features are:
• high dynamic actuator with specially designed
electronic driver
• closed loop controlled spool position
• 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
• meets relevant European EMC-standards
