Woodward 8563-701
Product Overview
A linear proportional electro-hydraulic servo actuator designed for diesel and gas engine speed control. It receives a 4–20 mA control signal from an electronic governor and converts it into precise rotary motion to adjust fuel rack position. The EG-B integrates hydraulic and mechanical components into a compact unit, widely used in marine and industrial engine applications.
