The invention concerns a fluid distribution and control valve, comprising a valve body (1) defining four internal zones (3, 5, 13, 15) connectable each to an external fluid circuit (U, 25, S¿1?,¿ ?S¿2?) and a mobile structure (2) mobile into at least four positions for selectively providing a fluid communication between two of said zones and isolating each of the two other zones. The invention is in particular applicable to a pilot's mask (M) supplying oxygen from a main source (S¿1?) or, if required, a second emergency source (S¿2?)
