A valve for supplying pressured air to vehicle air bags, includes a shuttle ( 20 ) with a valving member ( 80 ) having a precision polished seal surface ( 86 ) that presses against a precision polished sealed-against housing lower surface ( 50 ) of a housing ( 14 ) that confines the shuttle to sliding left and right. A recess ( 90 ) in the valving member can connect first and second holes ( 52 and 56, 58 ) in the housing lower surface, or isolate the holes from each other. The shuttle includes a shuttle frame ( 70 ) with a vertical bore ( 74 ) that receives a guiding part ( 82 ) of the valving member. A conduit extends from the valving member recess to a sealed region ( 102 ) at the top of the vertical passage to pressurize the sealed region with pressured air, to push down the valving member against the housing lower surface.
