Atos Type DLHZO Valve | DLHZO-TES-SN-NP-040-L73 | DLHZO-LEBQP | Digital Proportional Servo Valve

Atos Type DLHZO Series High-Performance Digital Proportional Servo Valves

Product Overview: The DLHZO Series represents the pinnacle of Atos electro-hydraulic proportional valves, featuring a high-response design available in Size 06 (NG6). What sets this series apart is the specialized “Spool-in-sleeve” construction, which eliminates casting irregularities to provide exceptional linearity and dynamic response. Equipped with Integrated Digital Amplifiers (TES or LEB), DLHZO valves enable high-precision closed-loop control of position, velocity, and force, making them the premier choice for high-end industrial machinery, plastics processing, and aerospace simulators.

Featured prominently are the standard digital control model DLHZO-TES-SN-NP-040-L73 and the enhanced performance specification DLHZO-LEBQP-SN-NP-060V71.

Key Technical Advantages:

• Servo-Level Precision: The precision-ground spool and sleeve assembly delivers ultra-low hysteresis (< 0.1%) and superior repeatability, rivaling traditional servo valve performance.

• Integrated Digital Amplifiers (OBE): The TES/LEB versions feature on-board digital controllers allowing for software-based parameter tuning, diagnostics, and fieldbus options (CANopen, EtherCAT).

• High Dynamic Frequency Response: Optimized electromagnetic drives ensure stable gain and phase even under high-frequency step signals, meeting the demands of rapid switching cycles.

• Closed-Loop Position Feedback: An integrated LVDT sensor monitors spool position in real-time, with corrections handled by the on-board electronics to ensure flow output remains independent of load pressure fluctuations.
