The trigger valve works in conjunction with the top valve to trigger your nail gun when the trigger valve is pressed, it creates a difference in air pressure between the air reservoir and the cylinder, which causes the top valve to open, most triggering the piston wrench valve.
A common problem is a failed o-ring on the inside, when this happens, air may leak from the trigger and the gun will not fire normally, replacing the trigger valve assembly has restored
