Abstract
An adjustable pneumatic conveyor tube booster valve for banding to the top of a conveyor tube with the booster valve inlet located remotely from the pneumatic conveyor tube. The booster valve is constructed from an annular rubber sleeve which flexes inwardly in response to high inlet pressure in the booster valve to permit flow of air into the conveyor tube but returns to its original shape when the pressure in the inlet drops to prevent back flow of material from the conveyor tube into the booster valve. An adjustable cap permits adjustment of gas flow into the booster tube.
