In my previous post I gave a link to another tread, and that gives you 2 possibilities.Originally Posted by Max
I buy mine at the local paintball store. (1.2km from my front door)
Otherwise, don't you have google in your favorites. Or can't you use the yellow pages and paintball shop in 1 sentance?
330mm long, 75mm diameter.and what are the dimensions of the 20oz co2 bottle?
Yes, in a lot of cases it's an adapted 1 kg powder extinguisher from the car scrapyard.
Yes, the tread of the size in the bottleneck of a normal paintball bottle (in a fire extinguisher it's even bigger, M25*2 or 4/3 NPT) allows you a let trough of over 126mm², and that is the max you get from a Burkert 5404, so not much to worry about.You would really want flow in at one end and flow out at the other but paintball tanks flow in/out is at the same end
How are those bottles adapted and can you use those bottles for a fp buffertank?
.
By adding in/outlets in the right kind of connectors.
No, testpressure 16 bar, workpressure max 5 bar.and can you use those bottles for a fp buffertank?
If you would try, the plastic handle/trigger will pop off. If you replace that with something stronger, the bottom will pop out. If you weld that up, you'll have a grenade.
And, in the modern feathers, a car powder extinguisher would be a tad big
what should i use to make a buffertank? for my main tank would it be possible to get a painball bottle, cut 10cm out of the middle of it then weld the two bits together like this:

also where can i get a dump valve? i have tried googling it but cant find any it comes up with something for cars
thanks.
It's nothing special - a ball valve will do.
OF THE CORRECT PRESSURE RATING.It's nothing special - a ball valve will do.
Max... your questions show a lack of understanding / competence...don't even try to make your own F.P. Buffer Tank... in fact I'd recommend steering clear of F.P.
There are however various paintball bottle sizes ... if you want a shorter bottle.. try a 3.5 oz as a buffer.
Cut a tank in half and reweld it, if you can weld ali as a professional , you could do it.
But to get it recertified, that will be another matter.
On dump valve, any manualy operated 2/2 valve of the correct pressure rating will do the job nicely. I even used adapted fire extinguiser valves for that job.
But simplest is a hydraulic 1/8 bsp ballvalve.
The dump vales you found for cars are more like the mandatory PRV we need. Pressure Relief Valves. In cars it's used to protect the turbo and inlet manifold from overpressure.
In the robots it's to have a safety feature in the pressurised parts. The PRV has to be set at the max working pressure of the lowest rated component, or at 1000psi, whatever is lowest.
sorry for my lack of understanding/competance,
i had tried to find smaller painball bottles but all the shops i looked at only stocked 20oz ones but cleary others are available.
i have been looking at the rules and think i understand what the rules require in a pneumatics system, i see that i will need my presure relief valve, my dump valve but i dont know if i will need a remote isolation valve if i use a standard paintball bottle?
