Abstract

An electromagnetically actuated piston slide valve and an assembly set for such a valve with which an NC valve and an NO valve can be fabricated. Such a valve of the NC construction type comprises a valve housing with corresponding connectors and a fluid passage. A slide coupled with a magnetic armature is provided for regulating a free cross-sectional area of the fluid passage. A first spring urges the slide in an opening direction and a second spring urges the slide in an opposite closing direction, wherein the first and the second spring are adapted such that, in the electrically unenergized state of the coil, the slide adopts a position in which the fluid passage is closed.
