From: ddrake01 The over pressure disks were changed in the 200 bar Swiss valves, not the Sherwood which are great valves. I'm just not happy with the risk of over- presurizing. What happens when the tank or manifold fails first? Lawyer: Mr. tank owner, this 16 yr. old boy was killed because you violated Federal law when you defeated the SAFETY RELIEF device in a valve that is under rated for the tank's legal rated pressure which is itself a violation of Federal law. This boy's LIFE was lost so you could get a few extra MINUTES of bottom time????? Those sure were expensive minutes Mr. tank owner, they'll cost you a few million--or whatever you got... The Sherwood socket I had seemed to have a more depth to it than other 300 bar DIN sockets. I beleive this is due to the design where the air comes into the socket. The metal on the back side of the socket ( where the dimple would be if it were a yoke or A clamp ) seemed to be extra thick compared to other high pressure valves. Motivation: I'd rather have the ability to switch between types of regulators and have 300 bar DIN valves with double O rings w/o changing bursts disks if I can. You know-have my cake and eat it too or "eat my pudding w/o my meat"! Yes, I know the A clamp wouldn't be good for much past 3000 psi, but I can always underfill, drain the tanks, or put them in ice-cold Lake Superior water! Again, does anyone know if the Swiss make a 300 bar manifold? DAVID DRAKE AHDNN1A.DDRAKE01@ED*.CO* ROMULUS, MICHIGAN EDS/GM POWERTRAIN 8-375-5467 (GM NET)
