About selection of valves and process and not a constructive
(OP)
I opened this topic for discussion on the criteria for use of valves. Usually there is always only the literature on the constructive part of the valves, and almost never on the criteria for selection and use of valves. Does anyone know any simple criterion or book, or form that describes a simple part of the process, use, classification and selection of valves? When using globe or butterfly. Available in the literature says that butterfly does not have good sealing properties, but manufacturers are already saying that their butterflies have excellent tightness. Already in the gas lines are not recommended. There is a criterion, link, site, a book that explains this process more fully?

Statoil (Norwegian oil company) have made a valve selection manual to be used for their projects.
Not to much info on why they have concluded as they have, but a lot of information on what type of valve to use in different services.

Try getting a hold of and having a look through this book:
Valve Selection Handbook - Engineering Fundamentals for Selecting the Right Valve Design for Every Industrial Flow Application (5th Edition)

Hello ENGMechanical,
In spite of the good references above, note that none of them will ever be complete. Since different applications with different medium compositions at different locations quite often require different solutions.
The best way to learn if a valve is suitable for an application is to ask for the experience of 'the guys in the field'.
.... experience and grey hairs seem to keep eachother in balance

Get a quote for your perticular application.
I've been on exactly the same PE plant through out different locations in the world and all had thier own character and needed different valves.

moltenmetal; SNORGY; terje61; Burdy and all others. My sincery thanks. As noted by our colleague, the question is a perfect stepping on each valve and the valuable experience overall in the field. Design a flowchart of a plant, or steam, PSA, Haber Bosch or a gas line, just so. Obviously a manual does not solve years of experience. I thank you all. The documents that you send is very helpfull. Best Regards. Edy

I had a Chinese speaker in the class the last time I put it on and he said that the translation was a bit literal, but not too far wrong.
For those that don't want to bother downloading an 8MB file, I suggest on that slide (with tongue firmly in cheek) that an adequate Safety Program might be a sign saying "Dying Right Here Strictly Prohibited". It is a translation from some Chinese characters.
