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. The valve is also used in manufacturing processes such as the petrochemical industry, chemical refining, and the food and beverage industry.

[ What is claimed is:] [1.]1. A valve for dispersing a fluidic substance into a carrier fluid comprising:(a) a conduit having a passage therethrough to carry the fluidic substance, said passage having an inlet end and an outlet end, said outlet end defining an orifice proximate said outlet end;(b) a housing encompassing said outlet end, said housing having a first retaining end and a second end fastened to said conduit and having at least one opening therein, said opening being adapted to allow a portion of the carrier fluid flowing past said housing to enter said at least one opening for dispersing said fluidic substance into said carrier fluid;(c) a valve seat connected to said conduit and circumscribing said orifice; and(d) at least one elastomeric member sealably retained in said housing, said member operatively connected to said retaining end by a force that yieldingly urges said elastomeric member into sealing engagement with said valve seat to control the flow of the fluidic substance therethrough.
