Abstract: A valve for dispersing a fluidic substance into a carrier fluid is disclosed. The valve is constructed from few moving parts and is particularly well adapted to distribute fluidic substances with little or no solubility in the flowing liquid into the carrier fluid. The valve is able to disperse difficult to dissolve fluids into the liquid stream by dispersing the fluidic substance into the carrier fluid at the stream's point of highest velocity and creating local turbulence at the points of dispersion. The design of the valve is such that the carrier fluid constantly flushes the valve's moving parts, and the valve is sealed from the dispersed fluidic substance to prevent jamming or clogging the moving parts by undissolved portions of the fluidic substance. The fluid pressure at which dispersal occurs and the volume of dispersal is precisely adjustable. The valve finds use in the irrigation of farmland, golf courses, athletic fields, public parks, and the yards of private homes.
