The first pic/link is to an old school Autococker that used CO2.
The second is a Dyna valve pin to a Sheridan that uses constant Air AKA a tank. The 12gram versions have a sharp pin forward of the valve seat to puncture the 12gram.
The third is of the same valve pin for a Sheridan but comes with more o-rings.
The fourth is for a VM68/PMI3 which was Sheridans stacked tube open bolt blowback.

The links were my attempt to match up with what I have to what I found on palmers site but those links have no data on length or cup seal materials, so that's why I asked if anyone knew anything about the 3 stems I described
Thanks for the help though I wish it was to my question

I answered the 1st question as to what guns based on the links provided.

The valve seats are a polyurethane or urethane base. The color doesnt mater much since it doesnt always match to hardness. One might be a little softer than the others. Soft seats seal better but I've found them to stick close. Stem finish is either going to be polished or blued. Again not much difference in performance as long as it is smooth.

What maker are you needing parts for a Sheridan or an AC?

I'm just trying to figure out what valve stems I have
Which ones go with what gun

I'll take pics tomorrow and hopefully that will help

Yeah the question was for the 3 valve stems I tried to describe
The 4 links were for valves stems I found but couldn't place the stems I have with those links
Sorry for the confusion on that
