A positive pressure actuated aerator valve assembly adapted to discharge compressed gas into the chamber of a bulk material handling structure. The aerator valve assembly includes a housing and positive pressure actuated valve. The housing includes a chamber adapted to receive compressed gas and a discharge piston slideable between an extended position and a retracted position. The valve includes a valve body having an actuator piston seat and a fluid vent passageway in fluid communication with the actuator piston seat. An actuator piston is slideable with respect to the valve body between a retracted position and an extended position. A positive displacement force is applied to the actuator piston, such as by the supply of pressurized gas to the valve, to slide the actuator piston from the retracted position toward the extended position whereupon gas within the chamber of the housing flows through the fluid vent passageway and the discharge piston is moved from the extended position to the retracted position by gas within the chamber to thereby place the chamber of the housing in fluid communication with the fluid passageway of the piston seat.
