Abstract
A valve device and method are provided that are operative to selectively divert the flow of air within a pneumatic carrier within a pneumatic carrier system. Generally, the device includes a pneumatic tube that is sized to permit the passage of pneumatic carriers. The pneumatic tube includes at least aperture in a sidewall of the pneumatic tube, an outer sleeve, and an actuator. The actuator acts on the outer sleeve to block and open the aperture to fluid flow in order to divert air in the pneumatic system. In one embodiment, the valve is disposed in a pneumatic system in conjunction with a pneumatic carrier handling device.
