Just wondering, does Trev from the Mighty Mouse team still do regulators? I still need a 10bar reg for my LP pneumatic system.
Yes he does, I got one a month or two back fitted in ceros works great, but not sure if he has any prebuilt send trev a pm
Cheers, will do.
Actually, something I also wanted to ask regarding the solenoid valve. What do the 1 or 2 'heads' at the ends of the valve actually do? And is a spring return suitable for a system like this?
Valve numbers, 1 - inlet 2 - outlet to ram. 3 - exhaust on a 3/2 valve solenoid activated spring return would work fine I would advice the use of a quick exhaust valve fitted directly to the ram to increase ram speed
Daniel,
Have 5 regulators ready to go, pm with your details.
Have had a request for a regulator adapted for paint-ball bottles, would anyone else be interested?
Trev
Would you be able to make one to fit a paintball bottle at 90 degrees to the regulator or would I have to use an external elbow?
Thanks,
Max
Max,
Will need to look at the standards for painball bottles and will re-post either here or elsewhere.
Trev
Does this look like a suitable solenoid valve?

I'd be interested in a reg to attach to a paintball bottle

Looks like I have another project......

Danny B, that solenoid valve can be used for lifters, as it has a low flowrate due the 1/8" connections.
In combination with Quick Exhaust valves it becomes another story. Woody has shown us the way to do that.
Trevor, I did adapt a reg of you in the past. Fitting it directly on a paintball valve just needs another nut. But then the bottle can't be horizontal as that will flood the reg with liquid CO2.
Your reg will survive,but the pressure spikes in the setup ain't funny. Lets hope on a good low pressure PRV then.
So as long as I add a QEV to the system, I should be fine?
Also, I was still worried about what you mentioned in your above comment, since I planned to have the bottles horizontal. Would the bottle's pin-valve help stop liquid reaching the reg, or is there another common way that I've missed?
A pin valve ain't good, you'll want an on-off valve on the paintball bottle. With a pin valve you'll need a seperate "isolation" valve meaning the connection on the Trevor won't be the one you're asking for.
This is an on/off valve.

And no, the valve won't stop any liquid CO2 from entering the system.
The solutions used:
Positioning the bottle under an angle so the valve is above liquid level. (simplest)
An up tube , meaning there is a tube in the bottle that sticks "up" so the hole is above liquid level.
Long coiled tube or hose between bottle and reg as heat exchanger/evaporator
Buffertank
Danny,
Will plan to have the reg at 90° to the bottle so by angling the reg up it will stop liquid at it's normal position.
I prevent fluid problems by running the reg outlet through a 6mm OD (4mm ID pipe) to a buffer tank. If fluid passes through the reg the reduced pipework allows the pressure to build and shut off the reg before it can damage anything. The longer the pipe the better...
Trevor
Trev,
I reckon I'll try your system too, since I'll almost certainly be going upside down at some point. When the bottle is at full capacity, is it literally full of liquid right to the top?
Also, I take it this would be a suitable hose for the reg outlet? http://www.ebay.co.uk/itm/New-Paintb...item3f202169c4
I can stick an adapter on it easily enough if the connection is different.
No, a CO2 bottle gets filled on weight, not pressure like most gasbottles. A full CO2 bottle at roomtemp is about 2/3ths full of liquid.Quote:

You realise that is 1 meter of braided hose you cannot shorten. But in theory that hose is strong enough to deal with the pressure.Quote:

Just trying to clear things up in my head, is the reg compatible with the on/off valve that you said I'd need on the bottle itself?
Nope, the thread on the on/off valve is exact the same as the pin valve.
Why should it be a different thread? It's a standard for paintball. The HPA (High Pressure Air bottles) have exact the same thread to connect to the markers.
And Trevors regs are originaly made for industrial bottle thread standard, and that's a tad larger than the paintball bottle thread. But that's just a question of changing the CO2 nut on the reg. Something Trevor and some other roboteers can do without any problem.
Sorry, I'm probably fretting more than I should be. I guess when you've never done something like this before, all sorts of questions come up.
No problemo, most roboteers will be glad to answer.
I would be interested in a trev for a paintball bottle
1 PM to Trevor should make that a possibility.
So I've managed to acquire 2 9oz paintball bottles, and I've decided to downsize the ram stroke from 100mm to 75mm in the hope that I can squeeze it into a tighter space.
Obviously, I don't know at this point how everything will be arranged within the robot just yet, but is it correct that I must be able to vent the main tank externally?
Most of the time the dump valve and the removable link are close to each other, to make the job of the arena marchal or pitcrew that dearms the robots easier.
So where in the system does the dump valve go?
That doesn't matter, as long the complete setup can be emptied by manualy opening that valve.
