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.

To me it is an octave key in that low
register.
Look at the fingering:
Eb 1 low eb 1-4
d 1-2 low d 1-2-4
Db 2-3 low db 2-3-4
c 1-3 low c 1-3-4
B 1-2-3 low b 1-2-3-4
So from eb down, pressing 4 lowers the pitch an octave
