The invention relates to a valve arrangement which can preferably be used in connection with a removal system comprising digester screens for digester liquids in cellulose digesters. The valve is characterized by a housing (1) with inlet openings (7) for digester liquid from each screen and at least one outlet opening (5) for the digester liquid from the screens and also at least one inlet opening (8) for digester liquid intended for back-flushing the screens and a rotor (10) in the housing (1) which is designed to shut off intermittently at least one of the inlet openings (7) from the screens and instead open the latter for the liquid for back-flushing.
