Abstract: A valve assembly with at least two valve modules is described, wherein the valve modules are arranged one beside the other in a line-up direction. The valve assembly also comprises an indicating device for displaying a state of the valve modules and/or of the valve assembly and/or of a component connected to the valve assembly. In the line-up direction the indicating device continuously extends over all valve modules.

Abstract: A modular system comprises a head module having at least one connection for an external bus signal on an external bus, at least one pneumatic supply connection, an electric supply connection and having a serial bus interface for an internal serial bus, an electric supply interface, a multipole interface and a pneumatic supply interface which are each led to the outside on the same side. The modular system further comprises at least one functional module having an internal serial bus line, electric supply lines, electric multipole lines and pneumatic supply lines which are each passed through from one side to the opposite side and which are each connected to a corresponding interface of the head module. The head module here converts serial bus signals into multipole signals and outputs these signals at the multipole interface.

Abstract: A valve device includes a housing body having a fluidic chamber which has at least one valve seat and a valve control member. The member includes a rigid frame having first and second opposed surfaces and being shaped with recesses, at least one of the recesses extending between the surfaces, a rigid actuating member and a flexible diaphragm on the first surface which is connected with the frame and actuating member by injection molding. The recesses are filled with, and sealing contours on the second surface are formed of, the diaphragm material. At least one valve body is formed by a section of the actuating member and a section of the diaphragm surrounding the actuating member. The valve control member is joined with the housing body so that the diaphragm closes and seals the fluidic chamber and the valve body is opposite the valve seat.
