A valve device for a domestic wastewater pipe is provided. The valve device includes a shutter and a fixing element to hold the shutter in the passage of the main duct between the inlet opening and the outlet opening of the pipe. The shutter is movable between a first configuration occluding the passage to prevent the flow of gaseous fluids, and a second configuration allowing the wastewater to flow from the inlet opening to the outlet opening of the pipe. The valve device includes a deformable main body partly defining the shutter, which occludes the passage of the main duct when the shutter is in the first configuration so that a pressure exerted by the wastewater on the shutter causes a reversible elastic deformation of said main body that moves the shutter from the first to the second configuration.
