Thanks for the replies all. I'll try to answer everybody's questions.

I have never needed a booster before. I'm running the same valve in my PST panther and it was plug and play no problems. It'll take a few weeks to get one sent to me.
Yes I have of course programmed the transmitter to the port on the receiver. Not my first ballgame.
I do not have a servo tester but they do function in the 12X servo monitor
I increased the travel to to 105%, same problem.
The channel is working both with a servo and the valve. The red and green lights do go back and forth as I throw the switch.

What appears to be happaning is that the valve actuates and then leaks all the air out of the orifice at the bottom of the valve in between the two air lines (the blue ones). Even when there is pressure it will not cycle the gear, they do not move. I'm not sure what is causing this. Is it something basic or is the valve not functional?
