I think I've probably got some words wrong, but I thought the setup was

main tank, which has
a valve which will open at a dangerous pressure
a valve to fill it with Co2
a valve operated outside the robot to isolate the bottle when not in use

downstream there is
a valve to release the gas into the ram
a dump valve operated outside the robot

Would I need a regulator, if so it would go between the isolating valve and releasing valve? Sorry, I'm a bit useless at all this!

The main tank is generally a paintball tank, with a screw fitting at the top attached directly to a Trev reg, preferably. I believe you can buy em those tanks on the Roaming Robots page, or even ask John on here. So, it will only have one opening really.

Yes you need a regulator. It would go exactly where I put it on that drawing, screwed directly to the paintball tank, ideally.

A regulator takes the full pressure in your cylinder and brings the pressure down to the 7 to 10 bar you want the ram to operate at. Otherwise you are running a full pressure system.

Simple enough, saves me a load of weight! The PRV is the pressure relief device? Just wondering, you said a 3/2 valve, meaning there is an exhaust, why is an exhaust required?
Also, the rules require an isolation valve, where does that go?

Oh, I get that, so a regulator is for LP systems where you want a lower power ram, and FP systems have no regulator, so are more powerful, just need stronger components. Thanks for the great answer. The 1000psi pressure relief device required for FP systems is the PRV Antazz refferred to in the drawing?

Before asking anymore questions, spend the rest of this evening reading through all the available threads on pneumatics, there's one just below this thread that's a good start. Then go on to use the search function.

You will still need a PRV in a LP system. The system I have drawn (ish) a diagram of is just Eric Jr (my LP FW) system. The exhaust allows the ram to return in conjunction with the spring/bungee. Isolation valve is on the paintball bottle itself, if you're lucky and have that type.

Most of this has been said/is being said in another thread at the moment, not to mention the dozens of other threads dedicated to this topic.

EDIT: What Gary said basically...

OK, I don't have any more questions now but I'll continue reading the other pneumatic thread, I've read up to about 3 pages, but theres something like 15 pages.

EDIT-Trevor doesent make regulators anymore, are there any particularly outstanding alternatives, or will any 10 bar regulator do?
