Characteristics of Valve Driver

The integral electronic driver combines all func­tions for optimal operation of the valve. Thanks
to its excellent dynamic 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 overcur­rent 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
