ORDERING CODE

The proportional directional valves XECV are designed as direct operated components for

subplate mounting. They are actuated by means of proportional solenoids with central thread

and removable coil. The position of the spool is controlled by integrated control electronics and

LVDT linear transducer sensor.

Features:

• Integrated control electronics

• Setup parameters by CAN interface

• Current compensation, gain current and ramps setting

• Monitoring of the valve by real time scope interface
