Description
I. Core Features
  • Direct-acting linear force motor drive: No pilot oil required, dynamic performance is pressure-independent, fast response, and anti-contamination.
  • Integrated electronics + valve core closed-loop: Built-in amplifier with valve core position feedback, high control accuracy, and low hysteresis.
  • Low power consumption: Low current consumption in and around the neutral position, energy saving.
  • Fail-safe: When power is lost, the valve core spring returns to the neutral position, and the system shuts down safely.
  • Installation standard: ISO 4401 specification 05 (NG10), flange mounting.
II. Key Technical Parameters
