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

Merle,
There are needle valves that are available that can control the volume of air that enters/leaves the cylinder. However, they are not designed to control the speed at which a cylinder operates. Teams have experimented with lower working pressures by adding a second pressure regulator downstream from the 60 PSI working regulator as described in the pneumatics manual. Please be advised that the valves do not seal much below 30PSI and so they become unreliable at reduced pressure.
There are many threads here that discuss this problem for the price of a search. The discussions will give you an insight to some of the team experience from past years.
