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.
