Thanks! I was wondering about that since the spec says it can extend flows flows of up to up to 25 GPM with only 4 GPM inlet flow. That is how I came across an article about how to apply pressure to both sides of a cylinder to try to get it to act like a cylinder the size of the shaft diameter. I'll just use a standard valve since I have a couple. The article on speeding up the cylinder is quoted below and I might give it a try also.
"There's a little-known trick that involves adding a 3-way valve (which actually means a 3-port, 2-position valve). It only speeds up the forward stroke, and reduces the splitting force proportionately.
Your extra valve has a "common" port that connects to one or the other of the ports, depending on which way the control leaver is set. The common port is connected to the ROD end of the cylinder.
One of the remaining valve ports is connected to the line that used to go directly to the rod end (call this position 1). The other port is Tee'd into the line feeding the BASE end of the cylinder (call this position 2).
When your auxiliary valve is set to position one, the cylinder operates normally under both the forward and backward strokes.
When the auxiliary valve is set to position two, the cylinder will operate only on the forward stroke. Pressure will be supplied to BOTH ends of the cylinder simultaneously. This seems counter-intuitive, since the cylinder will appear to be fighting itself. However one side exerts less force (because the rod occupies part of the surface area) so the cylinder extends. At the same time, the fluid forced out of the rod end circulates back to the base end, increasing the rate at which the cylinder moves.
Thanks again!
