A method for producing a disc valve device, in particular according to claim 1, with at least one first valve part comprising at least one first fluid port, with at least one second valve part comprising at least one second fluid port which is manufactured separately from the first valve part, and with at least one disc pack comprising at least one first valve disc and at least one second valve disc that is rotatable relative to the first valve disc, wherein flow-through paths are opened and/or closed depending on a position of the valve discs of the disc pack relative to one another, and wherein the first valve part and the second valve part are mounted to each other in such a way that the valve parts together form a disc pack receiving space by which at least the disc pack is accommodated, wherein an elastically deformable sealing element is elastically pre-loaded in the disc pack receiving space in such a way that in a mounted state of the valve parts the disc pack is pressed towards an abutment, which is in particular situated opposite the sealing element and in particular is at least connected to the first valve part. ### Claim 11 (depends on 11) The method according to claim 11, wherein the sealing element is elastically pre-loaded by pressing one of the valve parts against the respective other valve part or by pressing the valve parts against each other. ### Claim 12 (depends on 11) The method according to claim 11, wherein a relative position of the valve parts with respect to each other, and thus a pre-load of the sealing element, is adjusted by servo-pressing. ### Claim 13 (depends on 11) The method according to claim 11, wherein in at least one pre-mounting step, the sealing element is introduced into the second valve part and the disc pack is introduced into the first valve part, and wherein a defined pre-load of the sealing element is adjusted in that in at least one first pre-load setting step, the, in particular pre-mounted, first valve part and the, in particular pre-mounted, second valve part are brought into abutment with each other, and then in at least one second pre-load setting step, the valve parts situated in abutment are traversed apart once more by a defined path. ### Claim 14 (depends on 14) The method according to claim 14, wherein following the adjustment of the pre-load of the sealing element, in a joining step, the valve parts, which were arranged precisely relative to each other in the pre-load setting steps, are joined. ### Claim 15 (depends on 14) The method according to claim 14, wherein following the adjustment of the pre-load of the sealing element, in a joining step, the valve parts, which were arranged precisely relative to each other in the pre-load setting steps, are joined.
