Direct Lithium Extraction: Brine and Acid Handling
Piping, valves, actuation, and pumps for DLE's abrasive-slurry, corrosive-brine process loops — a young market with real vendor-published system recommendations behind it, not a generic mining cross-application.
Double Containment, Isolated-Bonnet Valves, and 75% Duty Cycling
Direct Lithium Extraction runs a continuous adsorb/desorb brine cycle carrying sodium hypochlorite, chlorine dioxide, and acids used as lithium-rich brine eluents — corrosive, cyclical, and regulated. Asahi/America publishes a specific recommended system for it rather than leaving DLE to a generic chemical-processing catalog, and Icon Process Controls independently maintains a dedicated Lithium Brine/DLE Processing application page. That's two vendors naming DLE by name, which is why it gets its own equipment sector here instead of folding into Mining or Chemical Processing.
Asahi/America's Own Recommended DLE System

| Pressure rating | 150 psi, plus drainage ratings |
| Containment design basis | Outer pipe designed to meet the EPA standard of at least 30 days of containment |
| Joining method | Simultaneous or staggered butt fusion |
| Leak detection | Cable installable on 2x6 and larger |
| Named chemistries | Sodium hypochlorite, chlorine dioxide, acids as lithium-rich brine eluents |
Full piping and fitting selection detail, including the material ladder (Proline PP, Super Proline PVDF, Ultra Proline ECTFE), is covered in the dedicated DLE Piping & Valve Infrastructure guide below.
Type-14 Diaphragm Valve + Series 19 MAV MultiPack
Asahi/America's named DLE valve-automation combination — chosen specifically for abrasive-slurry and corrosive-brine tolerance.
Type-14 Diaphragm Valve
Top-entry design isolates the bonnet so only the body and diaphragm ever touch the brine — the vendor-stated reason it tolerates abrasive slurry and corrosive brine without clogging or corroding.
Series 19 MAV MultiPack
Electric multi-turn actuator: 75% duty cycle (the spec that matters for DLE's continuous adsorb/desorb cycling), NEMA 4X, multi-color LED plus OLED and local pushbuttons.
Icon Process Controls: A Dedicated Lithium Brine/DLE Processing Application Page
Icon Process Controls independently publishes a Lithium Brine/DLE Processing application page — a second vendor naming this sector by name, separate from Asahi's piping and valve system.
| Product | Type |
|---|---|
| TI Series | Insertion paddlewheel flow meter |
| UltraFlo 1000 | In-line ultrasonic flow meter |
| ProPulse | Turbine flow meter |

DLE Piping & Valve Infrastructure
Double containment piping, diaphragm valves, and electric actuation for brine and acid handling loops — real dimensional, pressure, and containment specs from Asahi/America's own recommended DLE system.
DLE Pump Solutions
Surviving the lithium "valley of death" — pump architecture for corrosive, abrasive brine transfer where a wrong material call means a scrapped pilot run.
Frequently Asked Questions
What piping system does Asahi/America recommend for DLE brine and acid handling?
Duo-Pro double containment in PP, PVDF, or ECTFE, sizes 1x3 through 16x20, rated 150psi plus drainage — this is Asahi's own recommended system for DLE, not a generic double-containment cross-application.
What is the EPA containment design basis for DLE double containment piping?
The outer pipe is designed to meet the EPA standard of at least 30 days of containment — the real, quotable design basis for a DLE permitting conversation, joined by simultaneous or staggered butt fusion with leak-detection cable installable on 2x6 and larger.
Why does Asahi specify the Type-14 Diaphragm Valve for DLE instead of a ball or butterfly valve?
The Type-14's top-entry design isolates the bonnet so only the body and diaphragm ever touch the brine — the vendor-stated reason it tolerates abrasive slurry and corrosive brine without clogging or corroding. It's paired with the Series 19 MAV MultiPack electric actuator (75% duty cycle, NEMA 4X) for DLE's continuous adsorb/desorb cycling.
What chemistries does the Duo-Pro system need to handle in a DLE loop?
Named chemistries include sodium hypochlorite, chlorine dioxide, and acids used as lithium-rich brine eluents — real chemistries named against the Duo-Pro system, not a generic corrosive-service claim.
