Abstract
The plate-like valve elements (10 and 20) of the microvalve are provided with a plurality of valve seats and, respectively, corresponding valve members. The sealing surfaces of a secondary valve element (10) are respectively formed by molding to copy the sealing faces of a primary valve element (20) so that the sealing surfaces of both valve elements are completely complementary to each other. The sealing surfaces need no further processing such as machining. Despite liberal tolerances of manufacture a high precision register of the valve elements in relation to each other is ensured.
