When a system requires more than one ram or motor the first question to ask is do they work at the same time. If they do you must now consider the implications. Using hand valves might just result in less speed but because oil always takes the least resistance it might stop one movement altogether.
If in doubt I prefer to use one pump for each device and then I am sure that one “mover” will not affect the other. It’s very difficult to put right if you get this wrong!
If you know a better and reliable way I would love to hear from you.
Cheers
Bob
