The valve body (12) has a stop surface (48) facing the fluid outlet portion (40) and facing the armature (22). The stop surface (48) is designed to act as a stop for the armature (22) in its position furthest away from the fluid outlet portion (40). The stop surface (48) is a plasma nitrided surface.",
