3.3.9 Connecting the pneumatic lines

Festo P.BE−VTSA−44−EN en 0905e
Caution
The identification of the working lines on the 90°−connec
tion plate refers to the position of the 90°−connection plate
pre−assembled by Festo (see Fig. 3/7).
It is possible to mount the 90°−connection plate with the
exit for the working lines in the direction of the valve base
level, but this is not supported by Festo because the desig
nation of the ports no longer applies in this direction of
mounting.
Note
Use blanking plugs to seal all ports not required for the
·
valve terminal reliability.
If the VTSA... valve terminal is to be operated in con
·
formity with the ISO standard, the pilot exhaust air will
be vented non−ducted directly at the valve.
If the pilot air is to be vented ducted via port 12, the
·
valve terminal can, under certain circumstances, no
longer be operated with ISO valves from other manufac
turers. Note the instructions from the valve manufac
turer in this case. Conversion of the valve terminal to
ducted pilot exhaust is described in Chapter 5.4.1.
Mount the threaded connector or the silencers according to
the table below. The position of the pneumatic ports is shown
in Fig. 3/7. Lay the tubing afterwards.
Caution
If the VTSA/VTSA−F valve terminal is also equipped with
reversible valves with identifier T22CV−A, T32F−A, T32N−A
and T32W−A, see the instructions on connecting the valve
terminal in Sections 3.3.3 / 3.3.5 / 3.3.8 and Appendix B1,
Tab. B/4 and Tab. B/5.
