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.

Pneumatic valve and use thereof for a connected consumer

A valve device for a hydraulic circuit () divides the incoming volume flow into at least two pre-determined partial flows for supplying hydraulic consumers (V, V) of the circuit () and has at least one pressure balance () and at least one orifice. Since the orifice is embodied as a variable orifice () controllable by a proportional magnet (), the opening area of the orifice varies. A flow regulator is then realized and can switch the regulated volume flow and/or proportionally adjust the regulated volume flow in a defined manner.
