Product Overview
The ATOS DHRZO-P5E-012/25 is a high-performance proportional directional valve manufactured by Atos, a global leader in electrohydraulic control technology. This valve operates on a direct-operated proportional solenoid principle, utilizing a precision-machined spool within a robust cast iron body to provide infinitely variable directional and flow control of hydraulic fluid. The DHRZO series is engineered for systems requiring precise velocity regulation, smooth acceleration and deceleration profiles, and accurate directional positioning of actuators. With a nominal flow capacity of 25 L/min and a size 5 (NG6 / CETOP 3) interface, this valve serves as a critical control element in demanding industrial hydraulic circuits where electro-proportional responsiveness and repeatability are paramount.
