Outlet: 3"'
Media: Helium gas
Temperature range: -440 F to 70 F
Set Pressure: 0.25 psig
Flow Required: 12,000 SCFH at -300 F

Not sure how low the Flowsafe valves go. http://www.flowsafe.com/cry.htm
http://taylorvalve.com/ can make you a valve with materials accepted for cryo service, but they haven't tested them that way.
Best bet is probably an austenitic stainless body, like 316 SS.
Other materials to look for: Hastelloy, Inconel, Monel, aluminum (tho I haven't seen any Al valve), bronze/brass.
Only seal material I know of is teflon, but I've seen lots of different numbers on the lower temp limit.
Good luck.
