Product Overview
The ATOS DHZO-AE-071-S5 10 proportional directional control valve, supplied with the E-RI-AE-05F 10 digital electronic driver, is a high-performance servo-proportional valve assembly engineered by Atos (a globally recognized brand in electrohydraulic motion control). The DHZO series operates on a direct-operated proportional solenoid principle, where a precision-machined spool is positioned proportionally to the electrical command signal, enabling infinitely variable control of flow direction and magnitude. The integrated E-RI-AE-05F 10 digital driver provides closed-loop current control to the proportional solenoids, ensuring precise spool positioning, excellent repeatability, and minimal hysteresis. This valve is a critical motion-control component in industrial hydraulic systems requiring accurate velocity, position, and force regulation of actuators.
