The valve started it's life as a standard valve, then the solenoids were encased in a bolt on box then oil filled and pressure compensated with a bladder(hose) I also made a hose cutter so I can jettison the arm. I once built an arm that ran off convertible top hyd pumps. You can use one pump per function and it is a pump/valve all in one. They cost about 150 bucks on ebay and come with the cylinders. That is the way to go in my opinion. you buy four pumps and your done, the pumps just run in reverse for opposite oil flow,,,very simple. Oh ya I tested one and it gave me 1,200psi</span></div><div><span>Hank</span></div><div class="yahoo_quoted"

<div><font face="Arial" size="2">A few years back I was working on
a manipulator design but shelved it for lack of a suitable small multi
function hydraulic valve. I was looking for a small manually operated
valve. I was going to use air cylinders for their compact design and
reasonable pressure, plastic hoses rated to around 800 PSI and a multi section
manual operated control valve. I didn't want to design a build a valve
too. Has any one found something I missed? Maybe a gallon or less /
minute flow at maybe 300 to 600 PSI is what I was thinking about. </font></div>

What are you using for control valves?</font></div>

Manipulators</div>

<div>Alan,</div>
<div>I've seen the discussion. The smallest sub I know of with a manipulator
on board is the Deepworker. No exfra tanks there. Metacentric vs CG works in
all directions. Yes, you get movement and no it's not a problem in my
experience. I did operate the bigger subs but also smaller ones, to include
Aquarius, briefly in a DW, plus three different K-boats, so speak with some
experience. You put everything you imagine on a small sub, you get a big sub.
In any case, It's probably best to think of a psub as a work in progress. Get
the boat done, go play, scratch head, get more work done, go play, scratch
head......and so it goes.</div>

<div>Vance,</div>
<div>a couple of people have mentioned lately the problem of the shifting

countering it with</div>

more of a problem working on a </div>
