Abstract: A liquid (e.g., paint) distribution system comprising: at least one liquid reservoir; at least one liquid exchange assembly, wherein the liquid exchange assembly comprises at least one liquid exchange module; a plurality of liquid circulation lines disposed between the liquid reservoir and at least one liquid exchange module, wherein each the liquid circulation line supplies at least one liquid to the liquid exchange module; at least one liquid change valve module; and at least one liquid supply line in fluid communication between the liquid exchange module and the liquid change valve module. The liquid exchange module is configured such that the number of the liquid supply lines in fluid communication between the liquid exchange module and the liquid change valve module is less than the number of liquid circulation lines from the liquid reservoir to the liquid exchange module.
