the respective opening edge of the valve housing in a form-fitting or force-fitting manner, wherein the respective sleeve-shaped fastening element is adapted to apply a force to the respective annular sealing element in order to press the respective annular sealing element at the respective opening edge of the valve housing and at the valve piston and to effect a fluidic seal between the valve piston and the respective opening edge, wherein the respective sleeve-shaped fastening element comprises an inner sleeve section, which delimits a sleeve opening of the respective sleeve-shaped fastening element, and an outer sleeve section, which is connected to the respective opening edge of the valve housing in a form-fitting or force-fitting manner, and wherein between the inner sleeve section and the outer sleeve section a receiving area facing the housing interior of the valve housing is arranged, in which receiving area the respective annular sealing element is received at least in sections, characterized in that the respective sealing arrangement (117, 117-1, 117-2, 117-3, 117-4) consists exclusively of the respective sleeve-shaped fastening element and the respective annular sealing element, wherein the respective sealing arrangement (117, 117-1, 117-2, 117-3, 117-4) consists exclusively of two components. a valve housing, which delimits a housing interior, wherein the valve housing comprises at least two housing openings (105, 105-1, 105-2, 105-3, 105-4), which each fluidically connect the housing interior to an exterior of the fluid valve assembly, wherein the respective housing opening (105, 105-1, 105-2, 105-3, 105-4) is each delimited by an opening edge of the valve housing, a valve piston, which is rotatably arranged in the housing interior and is adapted to at least partially fluidically block or at least partially fluidically release the at least two housing openings (105, 105-1, 105-2, 105-3, 105-4) depending on a piston position of the valve piston, and at least two sealing arrangements (117, 117-1, 117-2, 117-3, 117-4), wherein a respective one of the at least two sealing arrangements (117, 117-1, 117-2, 117-3, 117-4) is arranged in a respective one of the at least two housing openings (105, 105-1, 105-2, 105-3, 105-4), wherein the sealing arrangements (117, 117-1, 117-2, 117-3, 117-4) each comprise a sleeve-shaped fastening element and an annular sealing element, wherein the respective sleeve-shaped fastening element is connected to the respective opening edge of the valve housing in a form-fitting or force-fitting manner, wherein the respective sleeve-shaped fastening element is adapted to apply a force to the respective annular sealing element in order to press the respective annular sealing element at the respective opening edge of the valve housing and at the valve piston and to effect a fluidic seal between the valve piston and the respective opening edge, wherein the respective sleeve-shaped fastening element comprises an inner sleeve section, which delimits a sleeve opening of the respective sleeve-shaped fastening element, and an outer sleeve section, which is connected to the respective opening edge of the valve housing in a form-fitting or force-fitting manner, and wherein between the inner sleeve section and the outer sleeve section a receiving area facing the housing interior of the valve housing is arranged, in which receiving area the respective annular sealing element is received at least in sections, characterized in that the respective sealing arrangement (117, 117-1, 117-2, 117-3, 117-4) consists exclusively of the respective sleeve-shaped fastening element and the respective annular sealing element, wherein the respective sealing arrangement (117, 117-1, 117-2, 117-3, 117-4) consists exclusively of two components.
