High speed valves
High speed valves
(OP)
Does anyone know of a souce for high speed valves. Needs for my application are as follows.
2-way
latchable
Must be able to complete 40+ cycles per second
Temperatures up to 200*F
Pressures of 3000 psi.

You probably want the Impervium alloy trim, too.
Superconducting coils are special order.

I think the flow will be closer to 750 mL/min.
I know I have seen some pretty quick cycle times for valves somewhere.
RE: High speed valves
Temperature ... _down_ to what?
Is the entire 3000 psi available for forcing oil through the valve, or is that just the system operating pressure?
Latchable? Mechanically? Electrically? Magnetically?

RE: High speed valves
I am incorporating this into a project for a friend of mine. The oil will be heated before operation so I'd expect the lowest temp to be about 170*F.
The 3000 psi is available for the valve.
Well, to minimize current draw I want the valve to open and then stay open with very little persuasion. And shut in the same manner. I am not sure but I believe what I am looking for is a magnetic latch.
RE: High speed valves
The last 3000psi valves I worked with had solenoid coils just a little smaller than a quart/liter oil can, and required ~100W to operate.
They did latch, accidentally, with no electric power applied, because of a phenomenon called 'flat end lock'. It probably wouldn't do what you want, because you have to relieve the hydraulic suppply pressure in order to unlock it.
So far, I don't think you've pushed your problem space into a possible union with any known solution space.

RE: High speed valves
After talking to a friend tonight I am reconsidering the hydraulic system altogether.
Instead we are looking at just using a solenoid to replace the valve and hydraulic cylinder altogether.
I'm sure this will bring a whole new set of problems to the game, but it is an option I should consider.
I was thinking a 48 volt system. It still has to operate to 40hz and be able to apply a pressure of about 200 lbs max.

And yes I realize 200lbs is a force. But I am pretty spacey.

OTOH, Clippard makes high-cycle life solenoid valves that will cycle pretty quickly. They're small, but you could parallel a few for more capacity.
