Optional Air-Release Valve

Manual 4-6
See Figure 5. Install an optional air-release valve for quick gun-response
applications over long distances. Use the air-release valve and two air
sources to fire several A7A guns by the same solenoid. When using this
option, the actuator air may be from any convenient air source but must
remain constant. Limit the size of the trigger air lines from the solenoid to
the gun to prevent spitting and other problems. An installation using this
option is shown below.
NOTE: Refer to the Options section for more information on the optional
air-release valve.
