DPZO-LEB, DPZO-LES
The Atos DPZO-LEB and DPZO-LES are high-performance, two-stage digital proportional directional valves engineered for demanding, high-speed closed-loop hydraulic systems. These piloted valves control both fluid direction and non-compensated flow parameters according to electronic reference signals.
- Operating Pressure : High Performance Range
- Application : Industrial & Mobile Systems
About this item
The Atos DPZO-LEB and DPZO-LES are high-performance, two-stage digital proportional directional valves designed for high-speed, closed-loop hydraulic control systems. Both models feature two integral LVDT position transducers (one on the pilot valve and one on the main stage) to ensure extreme regulating accuracy and fast dynamic response.
