Supply and Warranty
  • Delivery Time: Regularly 8-12 weeks, some in stock
  • Warranty: 12 months from the manufacturer
  • Origin: USA / Germany
Core Advantages
  • Direct-acting Design: No pilot-stage leakage, dynamic response independent of oil supply pressure, strong anti-contamination capability
  • Linear Force Motor: Bidirectional active drive, high thrust, overcomes flow and friction, precise positioning
  • Built-in Electronic Closed-Loop: Real-time valve core position feedback, high control accuracy, low hysteresis, and good stability
  • Low Power Consumption: Low current near the valve core center position, low standby power consumption
  • Wide Operating Condition Adaptability: High pressure, wide temperature range, wide viscosity range, suitable for harsh industrial environments
  • Easy Maintenance: No pilot filter, reduces maintenance points, long service life
Typical Applications
  • Injection Molding Machines, Die Casting Machines, Hydraulic Presses
  • Material Testing Machines, Servo Testing Stands
  • Industrial Robots, Automated Production Lines
  • Metallurgical Equipment, Papermaking Machinery
  • Aerospace Testing Systems
