Sure but you still push 120v thru the strand regardless of guage.
Is a power steering setup really that much lower pressure than a hyd system? Any of the ones I've worked with seem very similar in design

frankly i am still on side of why you even want smaller pressures / smaller GPM of hyd fluid vs just going with electrical. and at moment it is coming down to over all expense, and needing a spreadsheet basically for a price comparison. and then some con's/pro's. of the smaller hyd package vs electrical setup.
i have also been trying to think, what is out there, that uses multiple hyd cylinders and/or hyd motors, or like....
with electrical actuator for example, it would be easy to install or adjust sensors for fully extending/contracting the unit. so you are not destroying something. and then ya get into a whole mess of crud, over complicating things i would imagine with extra sensors and stops and like....for similuar setup, you would need to run both hyd lines and electrical wire to given spot... so you have them sensors...
well i guess i can take that back.... pressure relief valves, and making sure linkages, would allow fully extension and contraction of a hyd cylinder. but for a hyd motor vs electrical motor.... and say chute on a snow blower, and not wanting to turn the chut complete 360 degrees... i suppose you would quickly notice when ya turned the chute to the point it is blowing all the snow directly into the radiator and more so directly into your face LOL. but... hopefully idea gets across. (ughs been there done that on the old walk behind push snow blower)
hhmmsss i would imagine you would find a good amount of lower pressure and lower GPM items for robotic assembly lines and various manufacturing plants possibly.
LEGOS! pneumatics yAA!!!
i guess what max pressure do you want to work with, would be a starting point.... and then go from there for GPMs for a pump, and dealing hyd cylinders and hyd motors.
perhaps going with generic "air tools and equipment" of max 200 PSI. or 150 PSI you would be getting away from the more expensive and complex hose connectors that require more specialized and expensive tools when dealing with 1000PSI, to 1500PSI, 2000PSI, 2500PSI, 3000PSI, and on upwards higher PSI that you might find on current tractors and there hyd max pressures.
i doubt you would want to use air due to it compresses, but MAX PSI of 150 PSI, and using hyd fluid, you would more likely be able to use off the shelf fittings from any hardware store "within reason" of course.
perhaps a 12V on demand sprayer pump that can be used with a hand wand. some of those units can get up there in max PSI. and just going with a hyd fluid vs water and chemicals...
i wonder if you could find the lower PSI hyd cylinders and hyd motors. perhaps on some of the online stores that gear towards more for those "robotic wars" or what ever it is called on tv.
if ya keep the PSI down, abilty to use regular water valves, for drinking water and like could be had and used... though for life of me can't think of any multi function valves that deal with lower PSI...

i guess i am changing my tune from against. to with your thinking.

I would think running an automotive power steering pump for your micro circuit hydraulics would be a very practical way to do what you are describing. Maybe off an engine V-belt sheave. Find a steering rack and you've got an almost made-to-order chute rotator. I was thinking of doing something similar to offset my rear blade before I installed remotes.

You just need a flow divider valve. Very commonly used to run power steering from a big hyd circuit. If you want to limit the pressure just put a pressure relief valve in the low flow circuit. Flow divider valves are available with either fixed or adjustable flow on the controlled port. The remaining flow is used for the original higher flow circuit.

Some convertable cars used small hydraulics to put the top up and down.

YEs. They have small 12v pumps with reservoirs that adjust the drive up and down and for other things like trim tabs. The trim tabs pumps are easy to use and you could even put a nice control switch on your dash, some even have level indicators built in.
