Abstract: An assembly for controlling the eductive dispensing of multiple chemical fluids is described. The assembly is designed to detachably engage with existing eductor valve assemblies as either an original part or as a replacement part. The assembly comprises a plurality of selector gears that rotatably engage with eductor valve assemblies. The selector gears are in communication with a control gear. When the assembly is attached to a plurality of eductor valve assemblies an individual can control the rotation of multiple valve assemblies by rotating a single control knob.
