Abstract
Rotary valves and methods of using, manufacturing, and storing the same are provided herein. The rotary valve includes a rotor and a stator, biased toward one another to form a fluid tight seal. In some implementations, the rotor comprises an integrated flow channel containing a porous solid support. Frequently, the interface between rotor and stator is made fluid-tight using a gasket. Some implementations of the rotary valve include a displaceable spacer to prevent the gasket from sealing against at least one of the rotor and stator prior to operation, wherein when the spacer is displaced, the gasket seals the rotor and stator together in a fluid-tight manner.

(canceled)
A rotary valve comprising:
- a. a rotor 10 having an axis of rotation 16, an outer face 13 and a rotor valving face 12 opposite the outer face 13 and a pair of apertures 41, 42 through the rotor valving face 12;
- b. a stator 50 having a stator face 52 having a plurality of stator ports 53 in the stator face, each one of the plurality of stator ports 53 in communication with a fluid passage 54;
- c. a gasket 80 interposed between the stator face 52 and the rotor valving face 12, the gasket 80 having an inner gasket sealing face 81i and an outer gasket sealing face 810 and a pair of gasket openings 83 in alignment with the pair of apertures 42, 43 and
- d. a retention element 90 biasing the rotor and the stator towards one another placing the inner gasket sealing face 81i and an outer gasket sealing face 810 in a fluid tight arrangement with the plurality of stator ports 53 in the stator face 52.
