Servovalve - Overview - DesignAerospace LLC

A hydraulic servo valve is a servo (see Servo – Overview) with a device (either flapper nozzle or jet pipe) used to position the servo. The term electrohydraulic servovalve is often used because servovalves are controlled through an electrical signal. Servovalves are normally used when accurate position control is required, such as control of a primary flight control surface.
