how to speed the extension of pneumatic cylinders

[cmwilson13]

any year throwing or shooting is involved i see this asked. the simplest and easiest way to do this is to use more cylinders, if its going to slow add more cylinders while decreasing cylinder size to keep the force the same. your limited by the size of the input hardware not the number of them. 4 1/2 inch cylinders will extend much faster then 1 larger cylinder. the rules prohibit routing multiple valves to 1 cylinder so just add more cylinders. each cylinder has its own valve the only downside is it weighs more then the single cylinder solution
