Notes from the vendor documentation
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.

| Spec | Value | Source document |
|---|---|---|
| Type-14 diaphragm material options | PVDF / PTFE / EPDM diaphragm options, top-entry design isolating the bonnet from the fluid | Asahi/America — General Catalog (Valves, Actuators, Piping Systems, Welding Equipment) |
| Duo-Pro double containment piping (DLE system) | 1x3 through 16x20, 150psi + drainage ratings, outer pipe meets EPA standard of at least 30 days of containment | Asahi/America — General Catalog (Valves, Actuators, Piping Systems, Welding Equipment) |
| Named DLE chemistries handled | Sodium hypochlorite, chlorine dioxide, acids (lithium-rich brine eluents) | Asahi/America — General Catalog (Valves, Actuators, Piping Systems, Welding Equipment) |
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.
