Re: can we control the amount of air to control the speed of the cylinder?

In the past, my team has used 3 valves to control the speed of a piston. The first valve was a on/off valve to change the direction of the piston, and the other two valves had flow limiting exhausts on them. You send the output air from the first valve and then "T" it to the other two valves giving you the cases: both off, one venting, or two venting. This can give you a custom slow and fast speed for your piston, and if you wanted to you could add a number of valves to get a finer resolution, given that you can get each one to limit the air flow that much.
