D633 and D634 Series Direct Drive
Servo-Proportional Control Valves
with integrated 24 V Electronics
ISO 4401 Size 03 and 05 D633 AND D634 SERIES SERVO CONTROL VALVES
The D633 and D634 Series are Direct Drive Valves (DDV) with
electric closed loop spool position control.
These valves are throttle valves for 3-, 4-, and 2x2-way applications. They are suitable for electrohydraulic position, velocity,
pressure or force control systems including those with high
dynamic response requirements.
The spool drive device is a permanent magnet linear force motor
which can actively stroke the spool from its spring centered position in both directions. This is an advantage compared with proportional solenoids with one force direction only. The closed
loop spool position electronics and pulse width modulated
(PWM) drive electronics are integrated into the valve.
The integrated electronics of the valves is a new development
featuring SMD technology with pulse width modulated (PWM)
current output stage and requires a 24 VDC power supply The valve series described in this catalogue have successfully
passed EMC tests required by EC Directive. Please refer to the
respective references in the electronics section.
