<p>A pneumatic valve, in particular a pneumatic proportional pressure control valve, comprising a valve housing (3), in which a piston-like valve element (5) is guided axially movably in a guide (7) and, under the effect of an actuating device (9) for the valve element (5) and of a restoring device (11), which exerts a spring force and acts on the valve element (5) counter to the applied magnetic force (FB) of the actuating device (9), controls a media flow at least between at least a first media connection (13) and a second media connection (15) on the valve housing (3), is characterized in that, with the activation of 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 respectively pressure-effective surfaces, the spring force, the flow forces and the magnetic force.</p> |
