Abstract of the Disclosure An inline dispersal valve is constructed with a chamber into which a material to be dispersed into a fluid stream may be inserted. A first fluid deflector is used to direct fluid away from the fluid stream into the chamber to permit the fluid to absorb the dispersant, and a second fluid deflector, oppositely facing, that directs the fluid back into the fluid stream after it has passed through the chamber. The bottom of the chamber has a pair of openings in a line with each other which have an axis that i substantially normal to the axis of the fluid flow in a main stream. A rotatable plate having a pair of apertures of a specially designed tear drop shape controls the amount of fluid that flows through the chamber in accordance with the amount of available area to the fluid stream due to the alignment of the apertures with respect to inlet and outlet ports, respectively. The plate which contains the apertures is preferably a circular disc which carries a curved row of rack teeth. In one embodiment the rack teeth mesh with a spur gear which is coupled to a shaft that has a control knob on its outer end. As the control knob is rotated the spur gear rolls along the curved rack, causing the control plate to rotate. In a second embodiment a control plug is directly attached to the apertures such that when the plug is rotated the amount of fluid exposed to the apertures is increased or decreased directly and a chemical canister which may be keyed to the housing to prevent insertion of improper chemicals into the dispersal valve.
