Matching H valves and tank

[razorbackdiver]

I have a HP 120 with a K valve. It's rated for 230 BAR. I have an oppertunity to buy a new H valve for about $75, but it is only rate for 200 BAR. The shop I use often gives fills in the 3400 to 36 psi range. Can I used this valve or do I absolutey have to hold out for a 300 BAR H valve?

The working pressure of the valve has nothing to with the 200 bar vs 300 bar nomenclature. Read this:
