Estimating the term…
A material or 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. A remote activation function may be provided to facilitate initiating a color change procedure. In one embodiment, the remote activation function may be a pneumatic foot switch, while in another embodiment it may be an electrical switch, such as a membrane switch for example, mounted on a spray gun.
