Quick question from those that dive Mk 15.XX or BMR type rebreathers.
I am in the process of gathering a list of Swagelok parts to assemble the gas path plumbing on my BMR 500 and was wondering whether it is necessary to have check valves in the lines feeding the 02 and diluent addition to the center section as they both go through the same fitting on the center section. This is for the manual add (bypass valves) of diluent and 02 as well as for the metered 02. I will not be using a solenoid for metering in 02, rather I am going to use the Jetsam Kiss valve.
If check valves are required, does anyone happen to know the Swagelok part number? I find the Swagelok catalog confusing when searching online for specific parts
.
Thanks,
Marc
