The Woodward F-Series Modular Actuator is an electric bi-directional actuator with an integral driver, designed for engine-mounted position control on reciprocating engines in industrial and on-highway service. It accepts multiple position demand signal types and requires no hydraulics, pneumatics, or gear train, delivering reliable positioning with simplified installation.
