Maybe someone out there can help me find a
hydraulic valve.
I'm working on a design for a manipulating arm for
my sub, Persistence. The specific design I'm doing is for a K-sub, but it
could be adapted to most any sub with a brow.
I want to make it as powerful as possible and still
keep it compact and easy to operate. For a good power to size ratio and
good control, I've decided to operate it with hydraulics. I've located a
nice small 12VDC power unit that puts out 1/2 gallon a minute at 600 PSI
pressure. I consider that perfect because 600 PSI will deliver a lot of
punch but can be piped through plastic tubing, sparing the need
for bulky wire and rubber hydraulic hoses. I also found small compact
cylinders in a range of length that are rated at 600 PSI.
What I can't find is the directional control valve
I need. What I would like to use is, 12volt to 36 volt DC,
solenoid actuated, directional control, hydraulic valves that mount on one
common manifold. I can fine all I want rated at 30 gallons per minute at
2500PSI, but their big and really over kill for this
small application. I was thinking of trying to use pneumatic valves
but I'd have to experiment to see how they would work with fluid and also their
not rated for high enough pressure.
I would like the valve operated with
electrical solenoids rather then mechanical operated because that will allow me
to use wires to go through the hull, rather then two fluid lines for each of the
six cylinders I'm using.
I'm doing the design in Auto CAD and plan to
release it to the web, for anyone to use, once I have it
finished.
Can anyone help me locate the small valves?
For you European guys, sorry but I don't speak
metric very well but maybe you can convert.
*Six valve manifold block Five will work if
that's all I can get
*Six duel direction cylinder spools, with closed
center position
*12 - 36 VDC electrical solenoid
actuated
*Rated at 1/2 GPM flow minimum but not over
5GPM.
*Rated at, minimum 500PSI but not more then
1000PSI
Thanks, Dan H.
