ABSTRACT:
A microvalve includes a chamber, with a closing member being movable therein. The microvalve is made of two layers. The two layers of the microvalve are formed separately by being impressed as a mold into a moldable material and then filling the mold with metal by a galvanizing process. The two layers are joined together with the aid of a joining layer.
