摘要： Exemplary embodiments are directed to a rotary selector valve that includes a valve body that includes a rotor and a stator. The stator includes a first port for flow of a first flow material and a second port for flow of a second flow material. The rotor includes a groove for flow of at least one of the first flow material and the second flow material. The rotor includes a vent groove disposed between the first port and the second port for venting at least a portion of at least one of the first flow material and the second flow material to an exterior of the valve body. Exemplary methods of operating a rotary selector valve and C02-based chromatography flow systems including a rotary selector valve are also provided.

摘要： A fluid switching valve includes a first valve element (e.g., a stator) that has a plurality of first fluid-conveying features (e.g., ports), and a second valve element (e.g., a rotor) that has one or more second fluid-conveying features (e.g., fluid conduits in the form of grooves). The second valve element is movable, relative to the first valve element, 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. At least one of the first valve element and the second valve element includes a recess. The recess serves to reduce wear between the first valve element and the second valve element. The recess is arranged such that it does not overlap with any of the first fluid-conveying features or any of the second fluid-conveying features when the rotor is in any of the discrete positions.

摘要： 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.

摘要： A shear valve for use in a high performance liquid chromatography system. The shear valve includes a first valve member having a plurality of first fluid-conveying features, and a second valve member having one or more second fluid-conveying features. The second valve member is movable, relative to the first valve member, 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. At least one of the first and second valve members is at least partially coated with a protective coating that includes an adhesion interlayer and a diamond-like carbon (DLC) layer. The DLC layer is deposited on the adhesion interlayer via filtered cathodic vacuum arc (FCVA) deposition.
