how do make an air cylinder suck the wheel up

if you use 3-way spool valves you will only need 4

Yo DCNDED, pardon my ignorance but spool valve?

3 way valves in other words...they suck and are wayy to expensive

So SORRY abraham didn't realize buying 12 valves was so CHEAP, just offering another suggestion, i mean if theres anywhere for a spool valve its connected to your cylinders

Easier way to explain it, 4 valves per 3 wheeling cylinder Valve1 T Valve2 T Valve3 T Valve4, on the center T you will have your constant pressure from the tank. the 2 outside Ts go to ither side of the cylinder. for the wiring Valve 1 will be wired to valve 3 for power valve 2 will be wired to valve 4 for power that way you will only have to make one run for power, to the valves. For the grounds of course tie them all togeather and ground them. In my openion it rides like pure crap with pressure on both sides of the cylinder, very stiff.

I bet. It sounds like it would ride like crap with pressure on both sides. But it sounds like a convenient way of running the valves though.
