When installing a trial license (need to contact QlikView) or the Standard / Enterprise editions - the QlikView Expressor Connector is installed - this will enable QlikView applications to source data directly from a QVE dataflow and allow you to use the results in that manner.
It is demonstrated here in this video starting at or around 6 min 40 secs - 6:40
Without the trial or paide version - you can write data to .qvx files using the Write QlikView Operator. This is demonstrated in the video above and also here at or around the 11 min mark onward.
