Typical Applications
- Hydraulic CNC machine tools
- Automated production lines
- Mobile hydraulic machinery
- Energy-saving hydraulic power units
- Smart factory hydraulic systems
- Remote-monitored hydraulic installations
System Upgrade Considerations
The 4DM6 ELS/G24 B-DT-H is commonly evaluated in applications upgrading from:
- Conventional NG6 solenoid directional valves
- Legacy hydraulic directional control systems requiring digital precision
- Selected proportional valve modernization projects where stepper motor closed-loop control is preferred
Important: Verify manifold compatibility, spool function, voltage, and control logic before replacing existing proportional or servo valve systems.
The 4DM6 ELS/G24 B-DT-H is a compact NG6 / CETOP 3 digital proportional directional valve engineered for precision hydraulic flow and directional control in advanced industrial systems. Unlike conventional proportional solenoid valves, this model utilizes a high-thrust stepper motor actuator with closed-loop logic, delivering precise spool positioning accuracy up to ±1% while reducing susceptibility to hydraulic shock, fluid force interference, and step-loss.
Designed specifically for modern hydraulic automation, CNC equipment, energy-efficient power units, and intelligent machinery platforms, the valve integrates digital control architecture with optional 4G remote monitoring, enabling remote diagnostics, parameter tuning, and system optimization.
Its 90° rotatable motor structure allows flexible installation in height-restricted hydraulic manifolds, while automatic center return on power loss enhances fail-safe operational security.
