A system for selectively and controllably supplying pressurized fluids to dental or surgical tools requiring high pressure air and low pressure air and/or liquid. The fluids are selectively supplied through conduit means to a manifold including a plurality of passageways. Removably mounted upon the manifold are individual valve sets, each one associated with a tool. Each valve set is simultaneously opened or closed by the longitudinal movement of a shaft carrying spaced apart enlargements. The longitudinal movement is actuated by control air controlled by hangers upon which unused tools are hung. When a valve set is opened, fluids flow through manifold passageways, through the valve set, back through other manifold passageways and through conduit means to the selected tool.
