The valve seat module is a small, modular color changing block ; it is through the bolt, screw, etc.to connect multiple seat modules together.
Each seat module is equipped with two or more color change valves for quick selection of one or two return circuits ( paint or air / solvent ), and the number of seat modules is increased or decreased as needed ; it is mainly used for the selection of spraying color and the cleaning when performing color change. Every color change must perform a cleaning cycle operation ( air, dissolution ).
