Re: Slowing down the action of a cylinder with flow control, mechanical or via softwa

It seems like the ideal place to install a flow control fitting would be on the exhaust ports of the Festos, so that the flow control would only be used on the exhaust. In fact, I ordered and received some very nice $3 flow control fittings specifically designed for the exhaust ports of solenoid valves. But when I received them, I remembered that the Festo valves have these odd port threads (they are 7mm threaded ports, if I remember correctly), rather than the 1/8" NPT threading that I assumed they had, so we will need to use some kind of fitting adapters if we want to use them.
Sorry with using your terminology, but we did use the fittings. Just as you say above, we placed it on the exhaust port of the valve so it only effected the flow in one direction. Good luck and I hope you figure all of this out.
