Compared with D061-732D

Flow rate: 60 L/min (8 grades) vs 40 L/min (7 grades)

Feedback: Open loop (A) vs LVDT closed loop (D)

Connector: 4-core (A) vs 6-core (D)

Accuracy: Standard (open loop) vs Higher (closed loop) Structural features

Two-stage servo + jet pipe pilot: highly resistant to contamination, long service life

Integrated 24V drive: no need for external amplifier, wiring is simple

NG05 small size, large flow: 60 L/min is the higher flow level of this specification

Typical applications

Injection molding / die-casting machines: open-loop position / pressure control (medium-large flow)

Metallurgy: rolling mill hydraulic system, sheet metal rolling

Material testing: static loading, medium-low cycle fatigue

Precision machine tools, robot electro-hydraulic systems
