With the Tornado valve, AKA says to set the operating pressure at 250 PSI.
The regs that I would look at are
AKA 2 liter
Any PPS Stab
Dye Hyper 2/3
All of them work in the pressure range that you are looking for
One thing to look for is a reg with really good flow. The best one in that group is the AKA 2 liter hands down but it is also the most expensive.
