The moving drive portion of the force motor for an electromechanical servovalve is mechanicalkly constrained by slide bearing located on either side of the moving part to prevent it from rubbing against nonmoving parts, in turn, causing early failure and reliability problems. The connection between the force motor and the servovalve is adjustable to allow both the force motor to be electrically centered and the servovalve to be mechanically centered.
