That will take another two minutes or so... I have an inline valve (positioned after the KISS valve) It works immediately. (part numbers are in steevke's blog) For those that will argue that's yet another failure point... sure but I'm no alpinist. For those that think it's an additional risk. When it closes you can't press the KISS valve button. You'll know the very first time you try to manually add oxygen.
What may not be obvious from this post is that the residual trapped 02 in the regulator, lines, and especially in the the HP gauge hose, will continue to allow 02 to feed into the loop for a while after the cylinder valve is closed. The ball-valve right against the KISS valve allows instant shut-off of 02 flow and is exactly how my own KISS rigs are all set up. It's a good method. My only change is to have the valve ahead (upstream) of the KISS valve so I can shut off all flow in event of a broken line at the KISS valve or an unthreaded part, etc. Better to isolate gas in front of any subsystem rather than behind. This produces two advantages with one part. Typical alpine mindset.
