In accordance with the present inventive concept, there is provided a valve for administration of a plurality of drug fluids, such as cytostatics. The valve comprises: a housing having a plurality of circumferentially distributed primary inlets for receiving a respective one of the drug fluids and a secondary inlet for receiving a secondary fluid, such as a neutral fluid, an outlet, and a valve member arranged in the housing. The housing has a plurality of primary valve positions in each of which an associated one of the primary inlets is connected to the outlet, and a plurality of intermediary valve positions in each of which the secondary inlet is connected to the outlet. Moreover, the valve member has a outer surface sealingly engaging an inner surface of the housing, such that the primary and secondary inlets are sealingly connected to openings arranged in the outer surface of the valve member in each of the primary and intermediary valve positions, respectively.
