5 Table GS002S*options add the closed loop control of pressure (SP) or force (SFand SL) to the basic functions of proportional directional valves flow regu-lation. A dedicated algorithm alternates pressure (force) depending on the actual hydraulic system conditions. An additional connector is available for transducers to be interfaced to the valve s driver (1 pressure transducer for SP, 2 pressure transducersfor SF or 1 load cell for SL). The alternated pressure control (SP) is possible only for specific installation 12 pin connector is the same as /Z option plus two analog signals specific for the pressure (force) allows valve direct communication with machine control unit for digital reference, valve diagnostics and settings.

S* option add alternated P/Q control to the basic position ones. Atos also supplies complete servoactuators integrating servocylinder, digital Servoproportional valve and axis controller, fully assembled andtested.
