How do I make (2) impact markers fire simultaneously

Customer call for technical help regarding (2) air impact markers:

Customer: I have (2) model 78 mite-e-marks hitting opposite sides of a part.  When I fire the valve they are not hitting simultaneously and they are knocking the part out of my fixture.  Why are they not hitting at the same time?

Answer:  A single valve cannot be used to control multiple markers.  If a single valve is opened and sending air to multiple markers, the air will “always” follow the path of least resistance, resulting in one marker hitting before the other.
