I run three spool valves on several of my SMTA's. Plumb the inlet of your spool valve to the pressure port that points left and is at the top of the three port group. I believe the other two ports are for "delayed lift" and may be affecting your pressure. I have never used those ports.

There is no need to double the diameter as that will give you four times the lifting power.
