2.1. Existing valve control devices are set up in housings that feature a cover and a frame in which the valve spools are embedded. Between the cover and the frame, there is the circuit carrier with the electronic components. With the new valve control device, there is no longer to be any need for a housing, and the manufacturing process is to be simplified. 2.2. In order to save the housing, the valve control device is embedded together with the circuit carrier. The compound itself provides the housing of the valve control device. In the manufacturing process, following the mechanical and electrical connection of spools and circuit carrier, the spools are positioned in the embedding tool, and the complete arrangement is then embedded preferably with epoxy resin. 2.3. Due to their high reliability such valve control devices are suitable for antilock braking systems, anti-slip control systems, electronic brake servos, and electronic stabilizing programs in motor vehicles.
