yeah I have a 1/8" QEV that looks exactly the same and it works ok

teh 3 way is a NC valve.... it would be better to use a NO valve (NC will fill the gun when the button is pressed and then pilot it when you release it... so you'd need a spring loaded trigger/lever that would keep the stem of the valve depressed normally )
linky

if you don't want to build a special trigger for it then you might ask teh guy if he has NO versions
