A switchable valve for a sample injector includes a first valve member and a second valve member that can moved with respect to the other. The first valve member includes a plurality of ports, the second valve member includes a plurality of fluid paths. The plurality of ports include eight circumferential ports distributed along a circumference and one central port arranged at a central position of the first valve member. The plurality of fluid paths include three arcuate fluid paths so as to be couplable with at least two of the circumferential ports and one straight fluid path extending between the central position and a circumferential position so as to be couplable with the central port and one of the circumferential ports.
