Key Features
Pilotless Design: Linear force motor direct drive eliminates need for pilot oil supply, maintaining dynamic performance regardless of system pressure fluctuations.
Low Zero-Point Power Consumption + High Thrust: Low current near hydraulic zero point with sufficient force motor output margin for strong anti-jamming and anti-interference capabilities.
Built-in Closed-Loop Electronic Control: Valve core displacement sensor with PWM drive provides low hysteresis, high resolution, and excellent repeatability.
Strong Anti-Contamination Capability: Optimized valve core clearance and filtration scheme ensures reliable long-term operation in harsh industrial conditions.
