Can't find the blog, interesting idea, do you have a link to find the part number?
Thanks,

I put a very complete KISS Valve assembly sequence with isolation valve up on the web someplace a few years back. Tubby has taken his site down but the cache still resides here and the assembly is detailed:
DSkissvalve.html
I had a hard time gettign photos out of the cache (and what happened to Tubby anyhow?). In any event, here is the final photo from the series, showing all of the parts laid out in order. The valve is a chrome plated brass one that I buy for less than US$10.00. Works great. I shorten the handle with a saw to make it more compact. I also use custom made soft hoses, but with the correct fitting into the ball-valve, the original SS KISS hoses can also be used (in fact that is how my Spot KISS is set up)
The bottom line is that an isolation ball valve can be placed UPSTREAM of the KISS valve for about US$15.00. Please, guys, put the valve on the inlet side of the KISS valve. This way if the valve itself fails to leakage to the sea, the 02 can be turned off to conserve, the re-opened, a manual bolus injected, and then re-closed. And another note: Either make sure you have a second stage on the 02 side OR add an overpressure valve to the first stage. Otherwise a HP seat failed to creep will blow the hoses if the ball valve is closed.
