Fig. 7 shows the groups or 2-3-4-5-6 etc. multi-way valve that can be assembled from a basic valve according to the modular principle. The valve consists of the ring housing 21, the ring separating rim 239 of the valve foil roll bellows 22, which is provided with bores, slits or pores, the hollow connecting screw 25 = the pair of magnets 24 and the cover plate 29 with fastening nut 28. Almost any number of the ring housing can be attached to a hollow connecting screw 25 can be arranged in appropriate order.

For example, under the cover plate 29, an annular housing 21 with an annular partition 23, valve filament bellows 22 and a pair of magnets 24 can be arranged opposite one another, so that a changeover valve is thereby assembled. Both pairs of magnets 24 are then operated together. The valve foil bellows is longer than the ring partition. In this way, as already described in example 4, one valve can first be closed and the next one opened as the bellows continues to roll. This modular nesting can be continued in a large number and in multiple combinations. This is particularly beneficial for program controls.
