Atos DPZO-L Servo Valves

Proportional directional valves, piloted, with two LVDT position transducers and positive spool overlap for best dynamics in directional controls and not compensated flow regulations.

The valves operate in association with digital off-board divers.

The two LVDT transducers (pilot and main stage) grant very high regulation accuracy and response sensitivity.

With de-energized proportional solenoids, mechanical central position of the spool is performed by centering springs.

Spools regulation characterictics:

L: linear

S: progressive for fine low flow control

D and DL: differantial, for control of actuators with area ratio 1:2

D9 and L9: for regenerative circuit

Q5 and V9: for alternate P/Q control

Size: 10 / 32 – ISO 4401

Max flow: 180 / 1600 l/min

Max pressure: 350 bar
