Solenoid Recommendations

Double check the rules. In past years they limited us to one solenoid valve per cylinder. If that's the case this year, you can use two smaller cylinders with one valve each, to get the maximum speed.

Would two of these do well?

When I said two, I meant order two and have one per cylinder. I can see how what I said would be interpreted that way though.

I have looked through all the recommendations and I think this solenoid would work best. It's a 3-way 2 position and it seems good to me. I would just like confirmation from someone more experience with pneumatics to confirm it is good and also legal.

The same ones we use when only plumbing to one side of the cylinder. It is not the correct one for extend/retract. For that you need what Automation Direct calls a "5 port" Like this

The only real issue is the valve is rated for 115 PSI working pressure so you need a downstream relief valve per R77-D

We're planning to go with a setup like s_forbes. We have a 1.5" bore, 4" throw cylinder and we're shooting reasonably well using just the standard Vex solenoid/manifold through about a foot of tubing to the cylinder. We're optimistic about using the higher flow solenoid directly connected to the cylinder.

We're trying to figure out how to wire the solenoid. The picture only shows "12V" with arrows pointing to the two parallel leads. I'm not sure what that means. The PCM only has a black and a red wire. Do we connect red to one and black to the other? Does it matter which is which? What do we do with the third lead?

And oh, by the way, we'll be using 24V so we'll get a 24V solenoid.

Any guidance is appreciated.
