PAINT COLOR CHANGE AND FLOW CONTROL SYSTEM

摘要

PAINT COLOR CHANGE AND FLOW CONTROL SYSTEM A color change system for supplying paint to a remote spray head uses a paint manifold and suitable valving for supplying paint to either of two supply lines extending to the spray head to enable one supply line to be flushed with cleaning fluid and filled with paint of a new color while the other line is supplying paint of another color. Part of the necessary valving is located at the spray head and that valving includes pressure regulating valves controlled by air pilot pressure to accurately regulate the paint pressure and thus the paint flow rate to paint spray devices.
