8256-016

Product Overview Woodward 8256‑016 is a 24VDC rotary electric actuator (1724 model) from the EPG (Electrically Powered Governor) series. It forms a complete electronic speed‑governing system together with an electronic speed controller and magnetic pickup (MPU). It precisely drives fuel rack/throttle for diesel, gas and gasoline engines, supporting isochronous constant‑speed and droop speed‑droop control modes, widely used in generator sets, industrial engines, marine power units and oil‑gas prime movers.
