The "2" in the middle of the model number is the type 2, larger stem. The Ideal valve that folks often gush about is the type 1 stem, which is a good deal more precise.

52-2-11: Series 52, stem type 2, straight pattern.
52-1-12: Series 52, stem type 1, angle pattern (this is the common one for us)

There's a parker hr series metering valve that spanks the ideal available on fleabay right now. I think its even still cheaper than that ideal. Search parker metering valve and look for the h3l.

+1, go for the $25 Parker H3L, there is reason this metering valve is $450 in retail price.

CV value is important, but don't forget the orifice size.
orifice much larger but same CV, means less precision at low flow control, the perfect example are the swagelok bellow valves and the HOKE high pressure valves, both of the them have similar CV as some other metering valves, but with their large orifice, they are not for low flow control on our co2 systems.

detail of metering valves in the link below(signature), but can't do anymore update, not be able to add more info.
