Abstract
Disclosed is a pneumatic cartridge valve, especially for use as a pilot valve in a slimline pneumatic valve (1) for a compact valve unit. Said pneumatic cartridge valve has a drive part (2a) comprising an electromagnetic coil (3) for operating a valve part (2b) with a round cross section and has external pressurized-air ports (6). Said pressurized-air ports (6) extend to the outside in the area of the cylindrical outer surface of the valve part (2b). The drive part (2a), unlike the valve part (2b), has an essentially rectangular cross section, wherein the length (B) of its shorter side is determined by the winding diameter of the electromagnetic coil (3).
