Abstract
A valve armature of a solenoid valve includes an armature body having a blind hole in which an elastomer seal is vulcanized in. The armature body is manufactured in a cold forming process, in which a final axial linear dimension of the armature body is also determined. Furthermore, a valve having such a valve armature is presented.

A method of manufacturing a valve armature of a solenoid valve, having an armature body and an elastomer seal fastened thereto, comprising steps of:
- reshaping a cylinder-shaped blank to a final axial linear dimension of the armature body in a cold forming process, a blind hole being produced at one end of the blank and a valve seat-side end face being produced that surrounds the blind hole;
- and
- vulcanizing the elastomer seal in on an inner circumferential surface of the blind hole.
A valve armature of a solenoid valve, the valve armature having a valve set-side end, wherein on a valve seat-side end, the valve armature has a blind hole with an elastomer seal vulcanized into it.
A solenoid valve comprising a valve armature having a valve seat-side end, wherein on the valve seat-side end, the valve armature has a blind hole with an elastomer seal vulcanized into it, and comprising a valve body having a valve seat, wherein the elastomer seal is located opposite the valve seat and can sealingly contact it.
