Abstract
Modular circulating and dead end color changers are made from synthetic materials inert to chlorinated hydrocarbon solvents. Universal supply and return manifolds have relatively smooth and uninterrupted walls defined, in part, by inlet and return valve surfaces, for easy solvent flow cleaning. Circulating high pressure color changes have improved actuators and circulating means including bypass lines for continuously recirculating both selected and non-selected paints. Valve sealing is enhanced by improved valves and pressure drop across each module is minimized by modular construction regardless of the number of modules used.
