; A plug must be put in the last sequence T valve on the vacuum
header to prevent vacuum loss. If atmospheric valves are used,
you must terminate the vacuum line at the last atmospheric
valve.
3-7 Multiple Line System Piping Considerations
Figure 19
; Multiple line systems have separate material lines for each
material to allow different types of materials to be conveyed.
; Multiple line systems have separate pickup devices for each
vacuum hopper.
; Materials are often loaded from beside the processing machine
from gaylords, grinder takeoffs, and storage bin takeoffs.
3-8 Single Line Y-Tube System Considerations
Figures 15 to 17
; Single line Y piping systems use a common material line for all
vacuum receivers connected to a pump and are typically used
to convey material from a central supply to several stations.
; If you are installing a single line Y system, use Y tubes on the
material lines. A Y tube is installed with the branch arm
leading to the next station on top and the straight portion that
supplies material to the station underneath.
