Abstract
A pneumatic valve, in particular a pneumatic proportional pressure control valve includes a valve housing (), in which a piston valve element () is guided in a guide () under the effect of an actuating device () and of a restoring device (). The restoring device exerts a spring force and acts on the valve element () counter to the applied magnetic force (FB) of the actuating device (). The valve element controls a media flow between a first media connection () and a second media connection () on the valve housing (). With the actuating device (), the valve element () establishes a media-conducting connection () between the respective media connections (), 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.
