For high speed gun triggering (stitching) or for actuating the A7AA over
long distances, use an optional quick-exhaust valve. Refer to the
Options section for ordering information. The A7AA gun may also be
installed so that several guns can be fired by the same solenoid. This
requires using a quick-exhaust valve and two air sources.
When using this option, the actuation air must be constant but may be
from any convenient air source. It is also important to use a small ID air
line (
1
/
8
inch or less) for the trigger air from the solenoid to the quick
exhaust valve. An installation using this option is shown in Figure 5.
