A sleeve valve for fluid flow between a hydrocarbon reservoir and a well includes a first sleeve and a second sleeve which are relatively movable between a first position in which at least one opening in the first sleeve is aligned or misaligned with at least one opening in the second sleeve in order to admit or shut off the fluid flow. The first sleeve is provided with a radially movable sealing element that has a sealing surface adapted to rest against the second sleeve around the second sleeve opening, and at least one tension element presses the sealing element with its sealing surface against the second sleeve. A method for the assembly of such a sleeve valve includes a sealing element and a tension element placed in the outer sleeve opening and a clamping tool is adapted to the opening in the sealing element and moved outwards together with the sealing element until the sealing element is flush with the inner surface of the outer sleeve. Thereafter, the inner sleeve is inserted into the outer sleeve and the sealing element is allowed to rest against the inner sleeve and the clamping tool is removed.
