eters and Features Overview

The ATOS DLHZO-TES-SN-NP-040-L73 is a digital servo proportional valve featuring a direct-acting spool structure. It integrates an electronic amplifier and LVDT position sensor, delivering both high-precision control and high reliability. This valve is widely used in industrial automation applications.

Core Technical Parameters
Structure Type: Direct-acting four-way proportional valve with zero-shadowing spool design and precision-fit sleeve-to-body assembly
Flow Characteristics: Maximum flow rate of 40 L/min at 70 bar pressure drop
Operating Pressure: 0-25 MPa working pressure range
Nominal Bore: 10 mm
Operating Temperature: -20°C to 80°C (standard conditions) 
Dynamic Response: Optimized electro-hydraulic system design delivers servo-valve-level dynamics; static control accuracy ≤ ±0.5%
Electronics & Control Features
Integrated Amplifier: Digital amplifier (-TES type) supports factory presetting to ensure valve interchangeability
Communication Interfaces:
- PS: RS232 serial interface receiving analog signals via 7-pin/12-pin connectors 
-BC: CANbus interface supporting bus control and analog backup operation
-BP: PROFIBUS-DP interface compatible with industrial bus protocols
Position Feedback: LVDT inductive sensor enables closed-loop spool position control with 0.01mm resolution.
Installation and Compatibility
Certification Standards: Complies with CE certification (EMC immunity, Low Voltage Directive) and EN-982 safety specifications.
Connection Method: 7-pin (basic signals) or 12-pin (bus expansion) plugs, G3/4 threaded port.
Filtration Requirements: Recommended oil cleanliness ISO 18/15, lower than servo valve maintenance requirements.
Typical Applications
Precision Hydraulic Systems: Position/speed closed-loop control for injection molding machines, press brakes.
Industrial Automation: Robot joint drives, tension control in metallurgical equipment.
Testing Platforms: Dynamic performance testing of servo cylinders, fatigue test loading systems.
