RE: LFE valves
I found:
LFE - LA(E) & LF(E) Series De-Superheating Expansion Valves
LFE - Low Fugitive Emission Valves
LFE - Laminar Flow Elements
LFE - LFE gland packing
So what do you want?

RE: LFE valves
Okay, we now have the confirmation on the definition for the acronym LFE (special criteria for the valves) but we do not know if you want recommendations.
Did you only want the definitional or is there more?

RE: LFE valves
Dear Littleinch, our process engineering team says they want these LFE valves in the sour water stripper acid gas lines. Then I am thinking LFE valves are used here just to avoid H2S leakage? Because we have other toxic services where we do not use LFE valves.
RE: LFE valves
H2S is highly toxic and past a very low concentration cannot be smelt anymore, so human "detectors" are not able to be used.
Exactly how an LFE valve is different from a non LFE valve you would have to ask each vendor, but it is all about the stem seal type and packing / seals used.
