8250-828 | Woodward | EG3P 24 VDC Governed Industrial Actuator

Product Overview

The 8250-828 industrial actuator from Woodward is engineered for closed-loop governing systems that require fast, stable, and repeatable mechanical positioning. Designed for integration with Woodward electronic governors, this actuator provides precise modulation of fuel racks, air valves, and throttle mechanisms across a wide range of prime movers.

Available in electro-mechanical and pneumatic configurations, the actuator is optimized for harsh operating environments where vibration resistance, torque stability, and long-term reliability are critical. The EG3P-governed 24 VDC version delivers rapid response under fluctuating load conditions while maintaining accurate shaft positioning.

Key Functional Characteristics

The actuator converts electronic governor commands into controlled mechanical movement with minimal hysteresis and high positional repeatability. Its internal feedback mechanism ensures stable speed regulation, smooth load sharing, and dependable transient performance during start-up, load changes, and shutdown events.

Designed for continuous-duty industrial service, the unit supports both constant-speed and variable-load applications without performance degradation.
