Abstract

A pneumatic valve, in particular a pneumatic proportional pressure control valve includes a valve housing (3), in which a piston valve element (5) is guided in a guide (7) under the effect of an actuating device (9) and of a restoring device (11). The restoring device exerts a spring force and acts on the valve element (5) counter to the applied magnetic force (FB) of the actuating device (9). The valve element controls a media flow between a first media connection (13) and a second media connection (15) on the valve housing (3). With the actuating device (9), the valve element (5) establishes a media-conducting connection (17) between the respective media connections (13, 15), while allowing for the forces prevailing, on the basis of the applied pressures multiplied by the respective pressure-active surfaces, the spring force, the flow forces and the magnetic force.
