Hydraulics - Atos - Proportional Controls

Proportional valves modulate hydraulic parameters, in particular pressure and oil flow, according to electronic reference signals (normally ±10 VDC).

Atos, a leader in pioneering electrohydraulics, offers today one of the most advanced lines of proportional valves which allow similar or better performances in comparison with servo valves while maintaining the typical benefits of proportional hydraulics: less sensitivity, coarser filtration requirements, intrinsic stability, easier servicing and lower cost. Atos valves may be of spool type (originated from solenoid valves) or in cartridge execution (from logic elements) and can be grouped in two basic families having solenoids of different design:

ZO solenoid is an efficient solenoid (30 W) designed for direct-acting valves of size 03-NG 6 and 05-NG 10 and assembled in different options as follows:

ZO-A suitable for open of closed loop applications

ZO-T with integral electronic transducer, featuring high static and dynamic performances

ZO-TE as above plus integral electronic driver, preset in control loop, ensures fine functionality plus valve-to-valve interchangeability and simplifies installation wiring and system set-up
