    Abstract: A rotary shear valve having three-point stator seating is provided. Three contact points are predetermined between a bottom of the stator and a valve body rim and three clamping pads may also be predetermined. The three clamping pads and the three points of contact between stator and the valve body rim are corresponding and aligned when the rotary shear valve is assembled so that the clamping or compression forces on both sides of the stator directly oppose one another, thereby effectively canceling each other. In one embodiment, the stator includes three contact points on the bottom surface proximate the periphery of the stator to contact the valve rim and a gasket includes three clamping pads proximate the periphery of the gasket web to apply a compression force on the top surface of the stator above the three contact points.

  • Patent number: 8944295
    Abstract: A rotary valve meters the flow of particulate material from a supply source into a pneumatic conveying system and includes a central rotor rotatable within a cylindrical housing. The interior surface of the cylindrical housing is formed with grooves extending from pinch points at the inlet opening to facilitate the passage of particulate material past the pinch points without being trapped between the rotor vanes and the housing. The grooves are preferably formed in a configuration that has an increasing depth from the proximal wall to the distal wall, and preferably is configured with a spiraled surface shaped to increase the depth of the groove channel to a rounded end chamber at the distal wall. The groove channels can be oriented in alignment with a triangular ridge, in a circumferential direction perpendicular to the direction of movement of the rotor, or perpendicular to the angle of the triangular ridge.

A method of performing chromatography includes loading a sample with a valve in a load-state configuration that disposes a sample source in fluidic communication with a conduit disposed adjacent to a back surface of the rotor, and injecting the loaded sample with the valve in an inject-state configuration that disposes a solvent source in fluidic communication with a column via at grooves adjacent to a front seal surface of the rotor.

  • Publication number: 20130146797
    Abstract: A rotary valve meters the flow of particulate material from a supply source into a pneumatic conveying system and includes a central rotor rotatable within a cylindrical housing. The interior surface of the cylindrical housing is formed with grooves extending from pinch points at the inlet opening to facilitate the passage of particulate material past the pinch points without being trapped between the rotor vanes and the housing. The grooves are preferably formed in a configuration that has an increasing depth from the proximal wall to the distal wall, and preferably is configured with a spiraled surface shaped to increase the depth of the groove channel to a rounded end chamber at the distal wall. The groove channels can be oriented in alignment with a triangular ridge, in a circumferential direction perpendicular to the direction of movement of the rotor, or perpendicular to the angle of the triangular ridge.
