Abstract
A method of producing an electromagnetic valve includes deep drawing of a magnet housing, arranging a magnet coil, a magnet core and a plunger connected with an armature in the magnet housing, connecting a valve closing element which has a valve element for controlling a pressure medium flow, with the magnet housing by flanging a flared flange with a shoulder of the magnet housing relative to the valve closing element, and producing both the flared flange and the shoulder during the deep drawing of the magnet housing in a non-material-removing deformation step.
