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.

Abstract: This dispensing apparatus includes a shut-off valve having an inlet chamber connected to a water supply and an outlet connected to a hose extending to a remote dispensing station. A valve element is provided which separates the inlet chamber from a control chamber but includes passages communicating between said chambers. A servo line connected to the control chamber includes a trigger cut-off valve at the end of the hose remote from the shut-off valve. The trigger cut-off valve is closed to permit pressure build-up in the control chamber to close the valve element and the trigger cut-off valve is opened to relieve pressure in the control chamber and open the shut-off valve and permit liquid to be dispensed.
