Problems with packing installation in control valves

I have a question for everyone: inside the regulator’s adjustment sleeve, there is a metal gasket. Should graphite or PTFE filler be added to the lower part or the upper part of this metal gasket? Thank you all.

That is called a packing seat; it is placed below the packing

That is a positioning gasket; it seems to be at the very inside, and there should be another piece of polytetrafluoroethylene as well
