Woodward 8404-2059
Product Overview
A compact, integrated electric actuator designed for precise rotary control of butterfly valves, fuel racks, and throttle levers in industrial engines and turbines. It combines a limited angle torque (LAT) motor, gearbox, and integral driver electronics into a single unit, eliminating the need for external hydraulic systems. The actuator accepts standard industrial control signals and provides accurate positioning with fast response, making it ideal for harsh engine compartment environments.
