Your question is unclear and seems without any effort.
Who are you? What are you making? What have you done (and not just googling)? What is your goal? What is your current QA processes?
This is engineering forum, hence detail information is more appreciated.
Plus, not all questions can be answered (yet) by google. In short answer: no there is no simple flow chart as per your request. But ATEX directive is quite simple and clear.
ATEX 2014/34/EU is more of European thing. Not really sure what is the comparison with other region (some adapts, some not applicable, some less restrict, some copy paste with different name). I think US don’t follow ATEX, but they follow OSHA.
Not to be simplified, but ATEX is more of zoning stuff, and whether ones product MUST suit with the zoning requirement. See ‘zoning specification’ from wiki site which gerhardl advised.
How do you know your product should follow which zoning requirement? End user will tell you via their datasheet. Most safety personnel, process engineers of end user and authorized body knows this.
How do you know whether your product should be ATEX classified? Please spend some money to buy ATEX directive. This information will be very useful for you, and only for relatively small investment. Reason why we’re not sharing you this information is that this document is licensed aka copyrighted by European Commission
Note: manual (had operated only) valve is not subject for ATEX
So your product (as per RFQ from customer) should be ATEX’d, but you don’t have any, what should you do? Ask approved Notified Body or laboratory which is ATEX approved. Ask them what is the certification process. Asking = consultation, so most likely they will charge you for such questions. They have their own checklist. Once fulfilled, your ‘device’ will be send to their lab for combustion test.
Ta..da.. specific product series is certified for specific requirement. Good luck with other product.
Suggestion: be more clear with the inquiries, prepare small investment to buy some licensed documents. If this process don’t suit your portofolio, do what most vendors do which is coupling their (non-ATEX) product e.g. manual valve with well known (ATEX) product for example xyz junction box.

All valves will last for years, except the ones that were poorly manufactured; are still wrongly operated and or were wrongly selected
