II. Core Advantages
  1. ServoJet® Jet Tube Pilot: Highly resistant to contamination, no pilot oil source required, simple maintenance.
  2. Integrated Electronics + LVDT Feedback: In-valve closed-loop control, high precision, good stability, and strong anti-interference.
  3. Fast Response + High Pressure and High Flow: Suitable for high-speed, heavy-duty closed-loop systems (such as rolling mills, injection molding machines, and testing benches).
  4. Wide Media Compatibility: Adaptable to various hydraulic oils to meet different operating conditions.
  5. High Reliability: Low hysteresis and high repeatability, suitable for continuous production environments.
III. Typical Applications
  • Metallurgical Equipment: Roll gap control, tension control in rolling mills
  • Plastics Machinery: Servo control for injection molding machines and extruders
  • Testing Equipment: Material testing machines, hydraulic servo testing benches
  • Industrial Automation: Pressure/Position/Force closed-loop control systems
  • Construction Machinery: Precision control of heavy-duty hydraulic actuators
