The sleeve valve () comprises an outer and an inner sleeve () which are coaxially and rotatably arranged relative to one another, wherein in each of the sleeves () there is provided at least one through opening (). The sleeves () are rotated relative to one another with the aid of a suitable device, so that they can selectively be brought into an open, closed or other positions therebetween so as thereby to be able to control the fluid flow through the sleeve valve ().
