Difference from D061-7000D

732D: Standard valve core, zero opening, neutral position closed, industrial standard configuration

7000D: Special valve core code, mostly used for custom / high-end closed-loop systems Structural features

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

Integrated 24V drive + LVDT closed loop: no need for external amplifier, directly connected to PLC

NG05 small size: flexible installation, fast response

Typical applications

Injection molding / die-casting machine: closed-loop position / pressure control

Metallurgy: rolling mill tension, sheet metal finishing

Material testing: fatigue machine, static loading

Precision machine tools, robot electro-hydraulic system
