Sorry for the use of bandwidth for non-Vanagon content, but I need a
little help.

I need to source hydraulic cylinders - the double action type, where
hydraulic fluid extends  the ram,  then by way of a control valve
changes fluid flow direction,  then  retracts the ram. No return
springs.   I'm looking for a couple of these with a stroke of 10 to 12
inches. Although other strokes may work. I am also looking for the flow
direction valve. Usually a lever type device with three positions, --
open, flow one, and flow two. Additionally I am looking for hydraulic
pumps to supply the cylinders with the needed pressure. Surplus/used or
whatever is OK. Trying to keep my project costs down. If anyone has any
ideas or sources they could refer me to it would be appreciated.

Thanks,
