Abstract
Control system for multiple handpieces and associated devices includes a plurality of module control blocks secured in an assembly with a manifold that receives and distributes fluids to the blocks. Blocks contain cartridge valves, each removable through a single face of the control blocks for ease of access. The control blocks are adapted for attachment of auxiliary control devices. Flow control devices in the blocks are controlled by lifting of handpieces from hangers and/or by foot operated controls.
