The guides I know of are all based on either elastomer suppliers of products (sealings in general, O-rings) wich will be able to guide you regarding temperature, chemical resistence and pressure for known mechanical products (eg. o-rings etc)

or:

from larger suppliers of a wide range of for instance BFL centric valves. Bray, Tyco Controls and many others.

I think this would be the way to go.

As a curiosium: the German solenoid valve company Herion, now owned by Norgren, published in 1985 (In German only!) a very good handbook on different, common chemicals, chemical properties and crossrelated to different materials for body and sealings, again crossrelated to a limitid range of common temperatures and pressures, all materiales ranged as plus or minus.

Although limitid, and issued primarily for solenoid valves, this is still in my posession in a reachable shelf from my office chair.

I also would be grateful if somebody could point to something like this available today.

The Shell specification identifies specific packing materials per valve type and fluid service and then goes on to name specific packing suppliers.  I can't vouch for its usefulness but it's a start.  A request to Shell Global Solutions can be tried but they may be awkward!

ALso remember that different valves have different architecture that affects the packing.  Example: Some eccentric rotary plug control valves have standard extended bonnets, and the standard yarn-style packing serves to 750 degrees (F)  process temperature.  If you just look up the rated temperature of the packing, it's probably only rated to 450 (F) . Best to go with a manufacturer's rating of the packing he supplies than the ratings written in the packing catalog.
