A valve bag spout is mountable to a bag filling machine for being extended into the valve sleeve to discharge product into the valve bag. The maximum peripheral dimension of the spout filling tube is much smaller than the inner peripheral dimension of the valve sleeve while a wing assembly is mounted to the filling tube to have its wings extend outwardly of diametrically opposite sides of the filling tube in symmetrical relationship to the filling tube central axis. The wings diverge horizontally transversely outwardly in a rearward direction from the spout front discharge end portion. The front end of the wing assembly is circular while in a rearward direction gradually transitions to a flattened elliptical shape. The maximum height of the wing assembly is only slightly greater than the outer diameter of the filling tube and is much smaller than its maximum transverse horizontal dimension. Due to the provision of the wing assembly, the maximum vertical dimension of the valve sleeve opening is substantially less than if a frustoconical or circular spout portion were used to form a sealing fit with the valve sleeve interior.
