Sad that you persist, because you reveal ignorance about the partial system of brass instruments. Your upper reference notes are played as third partials. Your lower reference notes are played as second partials.
There is a fifth between the 2nd and 3rd partials. The 4th valve is one third of the (theoretical) length of the open bugle and lowers the instrument the interval of a fourth. The sum of a fifth and a fourth happens to be an octave but that doesn’t make the 4th valve an octave valve. The visual proof is, that an octave valve would have to be as long as the open bugle. It isn’t so.
