Dump Valve for Spread (help)

My trailer is a 2006 Great Dane spread axle reefer
let me start by saying i have read all dump valve threads on this forum and a few other sites as well.
I was thinking of using quick dump valve but many people have told me they are unreliable and expensive. That i would be best to use a regular dump valve and add a air brake valve (valve quick release) so when it senses the air pressure difference (when the electronic solenoid opens) it opens up and dumps the air quickly. I had a valve similar to this i believe on my old utility reefer trailer regular tandem axle. When i released the parking brake on the trailer it would dump all 4 bags in a matter of 10 to 15 seconds.
Where does the air brake valve get installed? before or after the electric solenoid and how do you connect the airlines since the air brake valve has 3 ports and 1 exhaust ports when a airline is like a 2 way function left to right (one air bag to another)
sorry if i sound confusing and thanks for the help
