Woodward 8405-028
Product Overview
A compact, high-torque electric actuator from the ProAct series, designed for precise rotary control of fuel valves, throttle levers, and dampers in industrial engines and turbines. It integrates a brushless DC motor, gearbox, and position feedback sensor into a single, sealed 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.
