I would caution that the stopping valve is NOT a 1/2 step valve, rather a 3/4 step valve, designed to compensate for the fact that when stopping in Bb the effect is more than 1/2 step. Thus that is why it is on the Bb side of the horn. There is no key change that is effective when using it, [A becomes somewhere between G and Ab for instance.]
Most good stopping valve slides are in two pieces, so that the player can choose between stopping and A horn.
