Valve assembly

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.
