Abstract

See full text

A shear valve assembly for use in a high performance liquid chromatography system. The shear valve assembly includes a stator having a plurality of first fluid-conveying features; and a rotor having one or more second fluid-conveying features. The rotor is movable, relative to the stator, between a plurality of discrete positions such that, in each of the discrete positions, at least one of the one or more second fluid-conveying features overlaps with multiple ones of the first fluid conveying features to provide for fluid communication therebetween. The rotor, including the second fluid-conveying features, is formed by injection-compression molding.
