Automated systems and methods for priming a fluid chamber of a fluid dispensing valve with fluid from a fluid material source that includes a vacuum source, a valve priming station, a vacuum switch, and a controller. The valve priming station has a boot, a vacuum chamber, and a vacuum channel in the boot. The vacuum channel connects with the vacuum source via the vacuum chamber. The boot sealingly engages a valve nozzle of the fluid dispensing valve so that the vacuum chamber connects the vacuum source with the fluid chamber. The vacuum switch couples with the vacuum channel via the vacuum chamber and has an opened and closed position based upon a vacuum level in the vacuum chamber. The controller is electrically connected with the vacuum source and vacuum switch and controls priming of the fluid dispensing valve based upon whether the vacuum switch is opened or closed.
