Trying to find more information regarding the material to be used for seal & seat under different corrosion conditions, operating temperature and pressure for valves.

The best I can find is: ABV Valve Catalog

However previously I have seen another catalogue which tells in more detail and categorize them into hard & soft seat/seals (but i lost it). Am wondering if there's any better info that gathers multiple seat/seal & it's operating conditions for easy reference?

Is PEEK good enough for normal temperature but High Pressure (up to 4500 class?)


Also can someone talk abit about explosive decompression (rapid drop in pressure) on Seals? Do we usually need to take this into account? Last time we had this issue on Viton A, later we switch to HNBR. But looking at ABV seal guide for higher temperature they use PTFE Lipseal & Graphite, do these materials offer high explosive decompression resistance?
