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 th…
