A pneumatic switching valve comprising a flexure-mounted armature, or "flapper", which is cycled under solenoid control, against a pair of orifices each of which controls a gas outlet port leading to a mechanical actuator. The flapper moves in a plane transverse the path of fluid supplied by two, confronting, supersonic jets, and passages in the flapper permit jet-derived fluid to flow toward one or the other of the actuators depending upon the position of the flapper with respect to the exit ports, as determined by the solenoids. A gap is provided between the flapper passages and the jet inlet nozzles, and serves as a bleed port affording automatic pressure relief.
