They are not part of the low-tier of valve manufacturers and you can be confident with their products.
A feedback on a whole company will be useless for you.
Both with Emerson and KSB, your user experience will vary on the kind of valve you need, the brand you choose, the design and trim you...
You might also ask if the valve is already equiped with a gearbox.
If so, it will be way easier to put an actuator on it.
Apparently you have most of the data you might need.
ISO couplig for actuator might be an issue for you as low-tier valve makers sometime don't sell ISO coupling on...
What kind of data are you looking for?
You can already gather a lot of information using only the norm your valve has been designed with. Maybe you can post a picture here.
Hopefully if the nameplate hasn't been painted over the last 20 years, you can ask your local Rep, RVAMeche is right.
H. Different codes will sometime provide different full bore sizes. But clearly not 1.5'' for a 2'' full bore valve.
API6D and API 608 both specifie the same full bore size : 49mm (1.94 inches) for a 2'' valve, (might be a little less for class2500 and above).
