Abstract

A method for arranging a valve element in an additional control valve device includes provides that, after a first position has been set, a valve plate is pushed onto the stem until the valve plate contacts the stop of a trapping magnet. The valve plate is then connected to the stem. This ensures that the fabrication tolerances are completely compensated by virtue of the first valve spring and the guiding of the valve element. After the second counter bearing has been secured in the guide, the holding of the first counter bearing in the previously determined first position is cancelled, which is then generally carried out by removing the tappet from the guide. After this has been done, the valve element automatically assumes a central position between the gantry magnet and the trapping magnet in the currentless state of the additional control valve device owing to the spring forces which then act.
