A valve for controlling a flow of a fluid between a first environment to a second environment is provided. The valve includes a frame that fits within an aperture in a divider separating the first environment from the second environment. Additionally, the valve includes at least one gate mounted and movable within the frame to control a flow of the fluid between the first environment and the second environment through the aperture. The gate includes a surface, wherein at least one portion of the surface includes a rough texture. The rough texture reduces coherent vortex shedding of the fluid as the fluid passes over the gate surface.

The sanding device of claim 1, wherein the anchor trip has a length, a width, and a thickness, and wherein the width is substantially equal to the thickness, such that the receiving gaps are substantially the same size when the anchor strip resides with its width spanning the elongate opening, as when the anchor strip resides with its thickness spanning the elongate opening. 17. The sanding block of claim 1, wherein the attaching means is configured for attaching said abrasive material to said body along the entire length of the body. 18. The sanding block of claim 1, wherein the length of the anchor strip is no longer than the length of the body such that when the anchor strip resides in the elongate opening, the anchor strip does not protrude outside of the elongate opening. 19. The sanding block of claim 18, wherein the anchor strip is characterized by an absence of any openings or recesses formed therein. 20. The sanding block of claim 1, wherein the anchor strip has a length, a width, and a thickness, and wherein the width is substantially equal to the thickness, such that the receiving gaps are substantially the same size when the anchor strip resides with its width spanning the elongate opening, as when the anchor strip resides with its thickness spanning the elongate opening; wherein the attaching means is configured for attaching said abrasive material to said body along the entire length of the body; wherein the length of the anchor strip is no longer than the length of the body such that when the anchor strip resides in the elongate opening, the anchor strip does not protrude outside of the elongate opening; wherein the anchor strip is characterized by an absence of any openings or recesses formed therein; and wherein said top surface and said bottom surface have a width of approximately 11/2 inches, and wherein said thickness has a dimension of approximately 3/4 inch. 21. A sanding device comprising: an elongate body having a length bounded by a first end and an opposing second end, and a width bounded by a first side and an opposing second side, and a thickness bounded by a top surface and a bottom surface, wherein the first side is substantially planer and wherein the opposing second side is rounded; attaching means for attaching opposing ends of a sheet of abrasive material to the first side of the body with said sheet of abrasive material wrapped about the body; wherein the attaching means further comprises an elongate anchor strip; wherein the first side of the body has an elongate opening formed therein, said elongate opening being defined by first and second opposing sidewalls that are inter-coupled by a bottom wall, said elongate opening being configured and dimensioned to receive the elongate anchor strip thereinto such that receiving gaps reside between the sidewalls and the anchor strip, respectively; wherein the anchor strip has a length, a width, and a thickness, and wherein the width is greater than the thickness, such that the receiving gaps are smaller when the anchor strip resides with its width spanning the elongate opening, and the receiving gaps are larger when the anchor strip resides with its thickness spanning the elongate opening. 22. A sanding device for use with abrasive sheet material, said sanding device comprising: a body having a top, a bottom, a first side, a second side, a first end, and a second end, said first side forming a right angle with said top and said bottom for sanding corners, said second side being rounded for sanding curved recesses; wherein said sanding device further comprises attaching means for attaching said abrasive sheet material to said body; wherein said attaching means for attaching said abrasive sheet material to said body comprises a groove in said body and an anchoring strip for holding the abrasive sheet material in the groove; wherein the first side of the body has said groove formed therein, said groove being defined by first and second opposing sidewalls that are inter-coupled by a bottom wall, said groove being configured and dimensioned to receive the anchoring strip thereinto such that receiving gaps reside between the sidewalls and the anchoring strip, respectively; wherein the anchoring strip has a length, a width, and a thickness, and wherein the width is greater than the thickness, such that the receiving gaps are smaller when the anchoring strip resides with its width spanning the groove, and the receiving gaps are larger when the anchoring strip resides with its thickness spanning the groove. 23. The sanding device of claim 22, wherein said anchoring strip is sized to hold the abrasive sheet material the groove with a friction fit. 24. The sanding device of claim 22, wherein the anchoring strip is insertable in the groove to grip the abrasive sheet material for attachment to the groove, and the anchoring strip is removable from the groove to change the abrasive sheet material. 25. The sanding device of claim 22, wherein the anchoring strip has a rectangular cross section. 26. The sanding device of claim 22 wherein said top and said bottom have a width of approximately 11/2 inches. 27. The sanding device of claim 22, wherein said thickness has a dimension of approximately 3/4 inch. 28. The sanding device of claim 22 wherein said body is constructed of a solid plastic material. 29. The sanding device of claim 22, wherein the body further comprises first and second opposing ledges that are formed in part by the first and second opposing sidewalls, respectively. 30. The sanding device of claim 22, wherein the second side of the body is rounded such that a boundary of the rounded portion forms a partial circle, wherein a radius of curvature of said rounded portion is that of a circle. 31. The sanding device of claim 22, wherein the first side of the body forms an elongate corner with the top and the bottom, and wherein at least a majority of said elongate corner is characterized by an absence of rounding. 32.
