Abstract

The invention relates to a valve particularly for transferring small portions of glue onto folding tabs of (cigarette) packs. A closing element (15) of the valve is actuated by different elements, that is to say, is moved between the open and closed positions, on the one hand by two permanent magnets (24, 25) arranged a short distance from each other and having aligned poles such that the closing element is permanently kept in the closed position by the permanent magnets (24, 25). On the other hand, an actuating element, which is configured as an electromagnet (23), acts to move the closing element (15) into the open position in a controlled way by overcoming the closing forces. The closing element (15) is designed in a particular way, that is to say, with channels extending along the outside in the longitudinal direction for the medium or the glue.
