Anyone no the mechanics of these

[ARFFMAN]

This is not necessary a Ford question but I have a 1994 f53 chassis with a Tag axle with tag brakes. Vacuum line from engine goes to a synchronize to tag brake Vacuum booster with a master brake cylinder. How does synchronize valve work/ I have vacuum coming in from engine and vacuum at the 2 ports that lead to booster, I would think slight air pressure would be needed to operate booster, I need someone to explain operation of sync valve.
