Claim:
1. An electromagnetically actuable high-pressure valving apparatus suitable for the field of gasoline direct injection or other fields using corrosive media, comprising: a one piece high-pressure valve with a high pressure side of about 280 bar; a valve seat which is arranged in a valve chamber of the valve and which can be closed off by a plate-shaped sealing element whose extent perpendicular to a direction of a valve opening is larger than in a direction of the valve opening and which is arranged between a low-pressure side (N) and a high-pressure side of the valve, wherein the plate-shaped sealing element is arranged so as to be movable between an open position and a closed position, having a movably arranged armature, and having an electrically energizable coil arranged so as to be suitable for acting on the armature, wherein the armature and the plate-shaped sealing element are arranged in the valve chamber, wherein the valve is in an open state when the energizable coil is unenergized and in a closed state when energized, wherein the armature is formed so as to be separate from the sealing element and wherein high-pressure valve components which are in contact with the corrosive media are manufactured from at least one of high-grade steel and hardened high grade steel, and wherein the armature is of a T-shaped form in cross section.
