Abstract
A feed center for powder coating material includes a hopper, an extraction duct, and a control valve. The hopper is in fluid communication with a fluidizing pressure source. The extraction duct is in fluid communication with at least one suction source. The control valve connects the extraction duct with an extraction port of the hopper. The control valve is operable between a first position for applying suction from the at least one suction source to the hopper, and a second position providing an exterior opening in at least one of the control valve and the first extraction duct for exhausting pressurized fluid from the hopper and/or collecting at least some of the air and powder that is exhausted from the powder.
