Valves comprise a valve body having a gallery coupled to an inlet and an outlet to facilitate a fluid flow therethrough. A plug is movably disposed within the valve body and a seat ring assembly may be coupled to the outlet of the valve body. At least one circular motion inducement feature is positioned in a portion of the valve body, the seat ring assembly, or both. The at least one circular inducement feature is configured to induce a circular motion in a fluid flow through the valve. Methods of creating a circular flow in a fluid flowing through a valve are also disclosed.

1. A control valve, comprising: a gallery comprising a central axis;an outlet in communication with the gallery; andan inlet in communication with the gallery and comprising a longitudinal axis laterally offset from the central axis of the gallery, wherein the longitudinal axis and the central axis
1. A control valve, comprising: a gallery comprising a central axis;an outlet in communication with the gallery; andan inlet in communication with the gallery and comprising a longitudinal axis laterally offset from the central axis of the gallery, wherein the longitudinal axis and the central axis do not intersect, and wherein one side of the inlet extending in a direction parallel to the longitudinal axis of the inlet is tangentially aligned with a portion of an inner sidewall of the gallery; anda seat ring assembly coupled to the outlet, the seat ring assembly comprising an at least substantially cube-shaped channel extending helically therethrough, wherein the cube-shaped channel has a square-shaped lateral cross section taken in a direction perpendicular to the longitudinal axis of the gallery; anda seat ring assembly coupled to the outlet, the seat assembly comprising an at least substantially cube-shaped channel extending helically therethrough, wherein the cube-shaped channel has a square-shaped lateral cross section taken in a direction perpendicular to the longitudinal axis of the gallery. 2. The control valve of claim 1, wherein a longitudinal axis of the outlet does not intersect with the longitudinal axis of the inlet. 3. The control valve of claim 1, further comprising at least one vane positioned in at least a portion of the inlet. 4. The control valve of claim 1, further comprising at least one vane positioned in at least a portion of the outlet. 5. The control valve of claim 1, wherein a longitudinal axis of the outlet is laterally offset from the central axis of the gallery. 6. The control valve of claim 1, further comprising: a plug movably disposed within a portion of the gallery and comprising a shaft coupled thereto;an actuator operably coupled to the shaft and configured to control a position of the plug within the gallery; anda positioner operably coupled to the actuator. 7. A method of creating a circular flow in a fluid flowing through a valve, comprising: providing the valve body of claim 1;flowing a fluid along a flow path;inducing a circular motion into the fluid flowing along the flow path. 8. The method of claim 7, further comprising providing at least one vane disposed within a portion of the flow path through the valve body. 9. A valve, comprising: a valve body comprising an inlet and an outlet each coupled to a gallery and configured to facilitate a fluid flow from the inlet, through the gallery and to the outlet;a plug movably disposed within the valve body and comprising a shaft coupled thereto;a seat ring assembly coupled to the outlet of the valve body; andat least one circular motion inducement feature configured to induce a circular motion in a fluid flow about a central axis of the gallery, wherein the at least one circular motion inducement feature comprises at least one vane positioned in the outlet of the valve body;wherein an inner sidewall of the inlet is tangentially aligned with a portion of an inner sidewall of the gallery, wherein the seat ring assembly comprises an at least substantially cube-shaped channel extending helically therethrough, wherein the cube-shaped channel has a square-shaped lateral cross section taken in a direction perpendicular to the longitudinal axis of the gallery. 10. The valve of claim 9, wherein a longitudinal axis of the inlet laterally is offset from the central axis of the gallery so that the longitudinal axis and the central axis do not intersect. 11. The valve of claim 10, wherein a longitudinal axis of the outlet is laterally offset from the central axis of the gallery. 12. The valve of claim 9, further comprising an actuator controllably coupled to the shaft and configured to control the position of the plug within the valve body. 13. The valve of claim 12, further comprising a positioner controllably coupled to the actuator. 14. A valve comprising: a valve body comprising an inlet and an outlet each coupled to a gallery and configured to facilitate a fluid flow from the inlet, through the gallery and to the outlet;a plug moveably disposed within the valve body and comprising a shaft coupled thereto;a seat ring assembly coupled to the outlet of the valve body; andat least one circular motion inducement configured to induce a circular motion in a fluid flow, wherein the at least one circular motion inducement feature comprises an aperture extending through the seat ring assembly and defining a shaped throat, and wherein the aperture comprises an at least substantially cube shape twisted about a longitudinal axis thereof, the aperture having a square-shaped lateral cross section taken in a direction perpendicular to the longitudinal axis of the aperture. 15. A control valve, comprising: a gallery comprising a central axis;the gallery, the outlet having a longitudinal axis extending in a direction parallel to and laterally offset from the central axis of the gallery;an inlet in communication with the gallery and comprising a longitudinal axis laterally offset from the central axis of the gallery, wherein the longitudinal axis and the central axis do not intersect, and wherein the longitudinal axis of the outlet does not intersect with the longitudinal axis of the inlet; andfurther comprising a seat ring assembly coupled to the outlet, the seat ring assembly comprising an at least substantially cube-shaped channel extending helically therethrough, wherein the cube-shaped channel has a square-shaped lateral cross section taken in a direction perpendicular to the longitudinal axis of the gallery.
