Hi, my 1968 Ford 4000 has auxiliary hydraulic but can only actuate a single double-acting cylinder. I need to actuate two separate hydraulic systems (i.e. two cylinders) independently. So I was looking at 6-port selector valves that would enable splitting the hydraulics.
But the ones I looked at are described as "open cross-over center" with continuous fluid flow. Should I be looking for a closed center type of selector instead? When I switch from powering the 1st cylinder to the 2nd cylinder, I want the 1st cylinder to stay locked in position under pressure. It sounds like an open crossover would relieve pressure on the 1st cylinder when switching the selector to the 2nd cylinder. Or is a "diverter" something I should be looking for instead (maybe its the same thing, not sure).
Or does it matter since I will be using the hydraulic control lever on the tractor to actuate, and not a separate control valve?
Thanks!
