I'm sure that as the valves get bigger, waiting in between each operation of the valve becomes more critical.
However, this is some data based on past experience with valves in the 2-4 inch range.
I once did some work in a plant that had lots of motorized valves. I was on a recontrol project. During the early phases, I'd noticed that some bright person had rewired two of the valves so that the limit switches were no longer in series with the motor coils. They were wired to PLC inputs only. Obviously, these valves had slightly different logic.
Later on I replaced the code for those two valves, I'd been meaning to get them rewired at the same time so the code was written for standard valves, but I forgot. So what happens? These valves just keep rotating and never stop. They weren't critical and the only person that noticed it, didn't think to mention it to me so they went until they failed. Took a couple days for the first one to melt down. Once the maintenance tech noticed it, he went looking for the other one (he knew there were 2 wired different) and found it still going but extremely hot. He replaced both actuators and all was well.
