Abstract
A servo valve for controlling an actuator comprising a housing, a first slide movable in the housing for controlling the flow of fluid to and from the actuator and a second slide mounted for movement in the housing. Both of the slides are movable in the housing during normal operation of the servo valve. Each of the slides is movable in the housing when the other of the slides jams. A jam sensor responds to either of the slides jamming for providing a corrective function for the servo valve.
