Core Functions

1. Integrated driver & position closed‑loop control, high‑precision proportional positioning, low hysteresis, fast dynamic response.

2. Large torque output, suitable for heavy‑load fuel rack and throttle valve driving of large engines.

3. Built‑in overspeed protection, overload protection, over‑travel protection and reverse‑polarity protection.

4. Supports base‑mount or valve flange‑mount installation, adaptable to all mounting attitudes.

5. Perfectly compatible with Woodward analog/digital governors, stable operation under strong vibration and high‑temperature harsh conditions.
