The valve comprises a discharge channel (19) through which the substance to be dispensed is fed, and a side air inlet (20). Said valve further comprises a mixing device (100) interconnecting the side pressurized air inlet and the discharge channel to form a uniform air/substance mixture. The valve can be placed in a series of positions, i.e. a closed position in which the channel and inlet are sealed, a flushing position in which only the inlet is open, and an operative position in which both the channel and the inlet are open. In the flushing position, air is expelled through the outlet to remove the substance remaining therein.
