See full text

A multi-path selector valve used in liquid chromatography and other analytical methods for directing fluid along alternate paths of a flowstream. The selector valve has a stator and a rotor. The dynamic face of the stator has a plurality of openings arranged along an inner ring, a plurality of openings arranged along an outer ring, and an annular collection groove formed in the dynamic face. The inner ring, outer ring, and annular collection groove are concentric circles. The rotor's dynamic face is configured to mate with the rear face of the stator, and has two fluid flow paths. One fluid flow path has one end at a rotational center of the rotor and another end of the fluid flow path is configured to be aligned with a stator opening along the inner ring. The second fluid flow path has one end that is configured to be aligned with the annular collection groove and another end that is configured to be aligned with a stator opening along the outer ring.
