ABSTRACT A pilot stage valve is disclosed having a control mechanism for moving an actuating arm in response to an input signal, a jet pipe moved by the actuating arm for issuing a jet of fluid, a sandwich constructed receiver having a first receiver plate and a second receiver plate, each having a groove in the surface thereof facing each other with a splitter plate between the first and second receiver plates, the first and second grooves receiving a differential amount of fluid dependent upon the position of the jet pipe with respect to the splitter plate, the grooves being connected to respective outlet ports. The control mechanism comprises a magnetic operator having a generally U-shaped frame comprising first and second arms each having first and second ends and a cross-piece attaching the first ends of the first and second arms together, a first rare earth magnet attached to the second end of the first arm, a second rare earth magnet attached to the second end of the second arm, an armature attached to the cross-piece of the frame and extending between the magnets, a coil wound around the armature, and a means for attaching the armature to the actuating arm of the pilot stage valve.
