Abstract
A powder paint recirculation block assembly for use in a powder paint transfer assembly, and a method of operation, is disclosed. The recirculation block assembly includes a powder paint recirculation block body having an intake flow passage directing flow to an applicator flow passage leading to an application flow control assembly and a return flow passage leading to a return flow control assembly. The angles (change in direction) through which powder paint flows may be minimized to minimize potential impact fusion. The pinch rubbers in pneumatic pinch valves of the application flow control assembly and return flow control assembly may be removable to allow for valve repair.
