Hey there,
This company is a vendor of all sorts of valves. You can start with this part of their website and start surfing around to see what is out there.

Those are the companies that they represent.
There are so many valves out there and many different reasons for using the various valves and choosing the options for body and trim materials, sometimes it is temperature, sometimes flow rate, sometimes the kind of fluid flowing, maybe pressure, how well does the valve have to seal....
So it would be very hard to make a book of that kind of stuff without it getting to be huge.
Here is a link to a valve book. I have never used or seen one of these books. Typically the valve vendors provide catalogs and information of the latest technologies and applications with respect to valve.

Good Luck!
