A gas transportation device comprising: an inlet plate having at least one inlet; a substrate; a resonance plate having a central aperture, wherein a convergence chamber is formed between the resonance plate and the inlet plate; an actuating plate having a suspension part, an outer frame and at least one vacant space; a piezoelectric component attached on a surface of the suspension part of the actuating plate; an outlet plate having at least one outlet; and at least one valve disposed within at least one of the inlet and the outlet, wherein the valve comprises a holding component, a sealing component and a flexible membrane, wherein the inlet plate, the substrate, the resonance plate, the actuating plate, the piezoelectric component and the outlet plate are stacked sequentially, a gap between the resonance plate and the actuating plate is formed as a first chamber, and a second chamber is formed between the actuating plate and the outlet plate, wherein while the piezoelectric component drives the actuating plate to generate a bending vibration in resonance, a pressure gradient is formed between the first chamber and the second chamber, and the at least one valve is opened, whereby gas is inhaled into the convergence chamber via the inlet of the inlet plate, transported into the first chamber through the central aperture of the resonance plate, transported into the second chamber through the at least one vacant space, and then discharged out from the outlet of the outlet plate, so as to transport the gas, characterized in that: the flexible membrane is attached on a surface of the holding component, and the holding component is controlled by a control circuit so that the valve is able to be placed in an open or closed state, wherein an accommodation space is maintained between the holding component and the sealing component, and the flexible membrane is disposed within the accommodation space, wherein the holding component has at least two orifices and the flexible membrane has at least two orifices corresponding to the at least two orifices of the holding component, wherein the at least two orifices of the holding component are aligned with the at least two orifices of the flexible membrane, respectively, and wherein the sealing component has at least one orifice misaligned with the at least two orifices of the holding component. an inlet plate having at least one inlet;
