The present invention relates to a rotary valve and to a chromatography system comprising such a rotary valve. The rotary valve comprising a stator with an inner stator face, and a rotor with an inner rotor face arranged in sealing contact with the inner stator face, the rotor (1) is rotatably movable to a plurality of rotor positions about a rotational axis (RA) relative to the inner stator face (202), wherein the stator comprises ports and orifices and the rotor comprises two or more rotor interconnection paths for selective fluidic interconnection of said orifices with respect to the rotor position and wherein the rotor interconnection paths are arranged to in a rotary position connect the first orifice (S) to the fourth orifice (LF), the second orifice (W) to the third orifice (LE). And in a rotary position connect the eight orifice (SP) to the seventh orifice (PCFP). And in a rotary position connect the eight orifice (SP) to the fifth orifice (TC), the sixth orifice (FC) to the seventh orifice (PCFP). And in a rotary position connect the eight orifice (SP) to the third orifice (LE), the fourth orifice (LF) to the fifth orifice (TC), the sixth orifice (FC) to the seventh orifice (PCFP). |
