A valve for administration of drug fluids, such as cytostatics, comprises at least one "drug inlet" for receiving a drug fluid and a "saline inlet" for receiving a neutral fluid. In a "drug position" of a valve member (300), the drug inlet is connected to an outlet (230) of the valve via a primary channel (310) of the valve member (300) and there is no connection between the drug inlet and a secondary channel (320) of the valve member (300) and no connection between the drug inlet and the saline inlet. In a priming/flushing position, the saline inlet is connected to the drug inlet via the secondary channel (320) and the drug inlet is connected to the outlet (230) via the primary channel (310).
