  • Color change for powder coating material application system
    Patent number: 10058884
    Abstract: A color changer has a common feed passage that is connected to two or more inlet passages. The common feed passage can be reverse purged in a direction that is opposite a direction of powder flow through the common feed passage. A valve element seals a supply port that connects the inlet passage to the common feed passage to eliminate dead space and form a near bore line seal. The valve element is an elastic material that expands in response to applied compressed air inside the valve element.
