(OP)
Under what circumstances should I consider a modulating, vs. non-modulating, pilot valve?

Modulating Pilot - when to use

RE: Modulating Pilot - when to use
One case where a modulating would not be recommended is if you have a high Joule-Thompson effect during discharge. In some cases, ice could potentially form (if discharging vaporizing water) and block the discharge.
There are certainly other reasons to choose one over the other too but those are my thoughts.

Here are some additional considerations...

If your system is constantly working over set pressure, a pop acting will keep blowing off, reseating, blowing off, reseating.....a modulating valve will keep constant discharge..(think of it a a pressure regulator action....working on discharge)...I would get my knuckless whacked by my old chargehand should he read this last bit.
