Abstract: A fluid module having a valve node is specified, which includes a base body delimited by an outer surface and having a central fluid space, and at least four fluid channels which are fluidically separated from each other and each open into the central fluid space, wherein at least two valve connections are provided on the outer surface, and wherein a coupling point is provided on the valve node, to which a coupling module is fastened, in which a connection channel is formed, which is fluidically connected to one of the fluid channels in the valve node, and wherein the coupling module includes a coupling valve which selectively unblocks and closes the connection channel. A fluid system having at least two fluid modules, and a method of cleaning a fluid system or a fluid module are furthermore specified.

Abstract: A valve manifold has a housing with a central mixing chamber and a shell surface. The shell surface of the valve manifold has at least two valve ports, with each valve port being associated with one valve. A first valve port has three openings, and additional valve ports each having three openings. A respective first opening of the valve ports is in direct fluid communication with the central mixing chamber, and the second and third openings of the valve ports are each in fluid communication with an inflow or outflow via a duct. A bottom of the mixing chamber, in relation to a plane arranged perpendicularly to a vertical longitudinal axis of the housing, has a slope towards the first opening of the first.

Abstract: A valve manifold has a housing including a central mixing chamber and a shell surface. The shell surface has at least two valve ports that are each associated with one valve. A first valve port has three openings and the additional valve ports each have at least two, preferably three openings. A respective first opening of the valve ports is in direct fluid communication with the central mixing chamber, and the second and third openings of the valve ports are each in fluid communication with an inflow or outflow via a duct. An external port is provided which is in direct fluid communication with the mixing chamber via a duct.

Abstract: A valve assembly has a valve manifold which includes a housing having a central mixing chamber and a shell surface, and further has at least two diaphragm valves which are each adapted to be attached to a valve port provided on the shell surface. A first valve port has three openings, and the further valve ports each have at least two openings. A respective first opening of the valve ports is in direct fluid communication with the central mixing chamber and the second and third openings of the valve ports are each in fluid communication with an inflow or outflow via a duct. Each valve includes inlets or outlets which correspond with the openings of the valve ports and which are each in fluid communication with an opening. Each valve is adapted to shut or open the flow path between the first opening of a valve port and the second or third opening.
