Apeks Flight intermediate pressure. Do I have to depressurise?

[Joneill]

Yes you are right I can not turn it off.
Yes your are right, I will add a second stage for purging. I think a second stage has more air flow than an inflator so purging is more effective.
Yes I will have to drain the tank to get the 2nd stage off.
I will leave the tank empty anyway if it is not in use. I think the first stage does not like permanent pressurizing. I fill it right befor diving and drain afterwards.

The idea of this argon tank is beeing small. If you have a 1 or 2 lt argon tank then the valve and DIN connector are about 20%(?) of the whole system. So I just leave them away.

A similar system is Poseidon's EBS poseidon EBS The EBS has an on-off- valve intergrated which of course is better then having none. And it needs no adapter, the EBS already has a M18x1.5 thread. But it's a bit more bulky than Apeks Fligth and much more expensive.

Curious - how do you fill this tank without a valve/reg connected directly to the tank?

See pic. I can not put it on another tank. The DIN/Yoke part does not exist anymore.

Apeks has this kind of system:

Can you share a picture?

Behind this cover is a one way valve. You feed 300 bar from outside, very simpel.

Looks good. Do you have a picture of the assembled unit? I found nothing in www.

Do you know if LP thread is UNF 3/8?
Do you know if I can add an overpressure valve?

the regulator is a DS4 or US4, so standard 3/8 UNF & 7/16 UNF

Thank you. The Apeks systems seems to be nearly as bulky as a normal valve plus regulator. But interessting anyway.

So your adapter replaces the DIN threads with a m18x1.5?

Yes
