  • Fluid control valve
    Patent number: 6682413
    Abstract: 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.
