I'm looking on Ali at small HPA tanks and a valve.

The tank is easy enough to sort...maybe a 1.5litre of 2litre is plenty for me.

I note that some valves only let out 1bar or 1.5bar (etc).

I'm needing an output of 200bar (my 9015 cylinder runs at 200bar).

So...is this the valve I need? Or can you put me on the right path please?

Thanks.

Have you looked at Best Fiitings in the UK?

Maybe more expensive, but the quality will be proven.

Why do you need to regulate the tank discharge pressure? I would just use a straightforward valve with a pressure gauge on your fill whip (or use the pressure gauge on your rifle) and shut the valve on the tank once you've reached your desired 200bar fill pressure? This is the way all my tanks work
