<p>A system and method of spray coating with individual spray coating guns mounted to an hydraulic circuit which supplies high pressure coating liquid from a pump and recirculates a portion of the coating liquid supplied to each gun through a restrictor in a circulation manifold to the pump. An adjustable pressure regulator reduces the pressure differential across the restrictor to reduce the amount of coating liquid recirculated to the pump without effecting the pressure of the coating liquid at each of the spray guns.</p> |
