Asahi specifically recommends the Type-14 for DLE valve automation — chosen for abrasive-slurry and corrosive-brine tolerance without clogging or corroding, because the top-entry design means only body and diaphragm touch the brine. Clearest vendor-stated valve-type recommendation for DLE in the corpus.

Asahi's own DLE recommendation is specific — Type-14 because its top-entry design means only the body and diaphragm ever touch the brine, not because it's a generic corrosion-resistant valve. On abrasive lithium-rich brine, a valve where the bonnet stays isolated from the fluid is the difference between a valve that clogs/corrodes and one that doesn't.
