"Valve to control a flow of a fluid between a first environment and a second environment, process to control the flow of a fluid.From a first environment to a second environment and mobile platform ".We describe a valve (10) for controlling a flow of a fluid between a first environment (E1), and a second environment (E2).The valve (10) includes a frame (14) which fits within the opening (18) in a partition (22) separating the first environment of the second environment.In addition, the valve includes at least one drawer (30) mounted and movable inside the frame (14) to control a flow of fluid between the first environment and the second environment.Through the opening (18). The drawer (30) includes a surface (5), in which at least a part of the surface includes a rough textured (70).The rough textured (70) reduces the flow of coherent vortex of the fluid as the fluid passes over the surface of the drawer (5).
