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 centred position in both directions. This is an advantage compared with proportional solenoids with one force direction only. The closed loop spool position control and pulse width modulated (PWM) drive electronics are integrated into the valve. The integrated electronics of the valves features SMD technology with pulse width modulated (PWM) current output stage, and requires a 24 VDC power supply
