Abstract
A valve includes a valve housing having first and second regions, at least one valve chamber configured to be pressurized with air and including an actuating element for opening and closing a valve opening and an actuator for actuating the actuating element, both arranged in the first region. A printed circuit board extends into each valve chamber and to electrically operate the actuator, the printed circuit board(s) being connected to a common main printed circuit board arranged in the second region. Each valve chamber is surrounded by boundary surfaces closing the valve chamber in a substantially gas-tight manner. An open space open to at least two oppositely disposed sides of the valve housing extends between at least two of the valve chambers, and a connecting member of the printed circuit boards extends through connecting openings of the boundary surfaces of adjacent valve chambers and the open space. A sealing material located in the open space encloses the connecting member and the connecting openings in a gas-tight manner at least in the direction of the oppositely disposed sides. A method of manufacturing such a valve includes manufacturing a conductor element including the printed circuit boards and the main printed circuit board; introducing the conductor element into the valve housing; and filling the open space at least in part with the sealing material from at least one side after the introducing step so that the sealing material seals the connecting member and the connecting openings in a gas-tight manner at least in the direction of the oppositely disposed sides.
