Woodward 8404-205 ProAct Analog Electric Actuator Module

Product Overview

The Woodward 8404-205 is a ProAct™ analog electric actuator designed for precise throttle and fuel control on diesel and gas engines. It combines a high-torque electric actuator with integral driver electronics in a single compact housing.

This integrated design eliminates hydraulic governors and external driver modules. Therefore, installation complexity and long-term maintenance requirements are significantly reduced.

Using Limited Angle Torque motor technology, the actuator delivers smooth rotary motion with accurate positioning. Moreover, it ensures stable speed regulation during rapid load changes.

The 8404-205 is engineered for continuous operation in demanding industrial environments. In addition, its sealed enclosure protects internal components from vibration, dust, and temperature extremes.
