Dump & Isolation Valves

[psychostorm]

Burst disc?
A male M25 connector isn't much use. The bottle isn't empty, it's both full & charged. I can't take the valve off now.

So this is connecting the main tank to the rest of the system? Then you need a co2 nut on the end of a hydraulic hose ideally.

Not ideal. I'd have pipe a system back to the fire extinguisher valve to fit the the on/off & dump valves.
I suppose if I load the bottle the other way round but then I wouldn't be able to access the fire extinguisher valves in the even of an emergency.

I also have no experience of making hydraulic hoses of any description.

Yes of course, for a main tank you'll require fitting a burst disk somehow... The fitting looks fat enough to have a 9mm hole drilled and tapped on the side to fit one.

I do, and it's not something I do at home. I usualy go to my old employer and have a hose made to fit.

On the other hand, I'm perfecting the setups so there ain't a need for heavy hydraulic hoses. Smaller, lighter and cheaper, what else do you want?

Recommendations for a dump valve?

Any small ballvalve that can take the pressure.
