Asahi/America
Thermoplastic ball, butterfly, check, gate, and diaphragm valves; Series 19 electric actuation; Proline/Super Proline/Ultra Proline piping; and Duo-Pro double containment for DLE and corrosive chemical service.
What LibertyCES specifies from Asahi/America
Ball valves factory-equipped with an off-gas vent hole for sodium hypochlorite service. Butterfly/check lines handle sulfuric, hydrofluoric, and nitric acid plus oxidizers and caustics.
NEMA 4X electric actuator with stainless steel trim. Recommended pairing with Type-14 Diaphragm Valve for Direct Lithium Extraction brine service.
Three chemical-resistance tiers of industrial piping — Ultra Proline specified for sulfuric acid where standard PE isn't sufficient.
Purad pipe extruded on dedicated ISO 5 equipment; Asahi's Lawrence Custom Fabrication Division cleanroom (spool welding, bagging) is a separate ISO 6/Class 1000 space. For UPW, WFI, semiconductor, and photovoltaic service — 20-315mm, up to 230 psi.
150 psi min at 68°F (50-yr), H2 Ready. Real 2015 installation: 1/2" Chem Proline spool pieces replaced failing CPVC in 50% caustic service for a semiconductor OEM, fitted without redesign.

Frequently Asked Questions
Why do Asahi/America ball valves have a vent hole?
To prevent off-gas buildup in sodium hypochlorite applications — a factory-equipped 1/8" vent hole. This is a valve-level confirmation of the same off-gassing hazard already documented at the pump and tank level for sodium hypochlorite service.
What is the difference between Proline, Super Proline, and Ultra Proline?
Proline is polypropylene (standard chemical resistance), Super Proline is PVDF (higher chemical/temperature resistance), and Ultra Proline is ECTFE/Halar — the highest resistance tier, specified for sulfuric acid where standard PE piping isn't sufficient.
What valve/actuator combination does Asahi/America recommend for DLE brine service?
Type-14 Diaphragm Valve with the Series 19 MAV MultiPack electric actuator — the diaphragm valve's top-entry design isolates the bonnet from the fluid so only the body/diaphragm (PVDF, PTFE, or EPDM) touches the abrasive, corrosive brine.
Does Asahi/America manufacture piping for semiconductor and high-purity applications?
Yes — Purad (UHP PVDF) pipe is extruded from ultrapure virgin resin on dedicated equipment in an ISO 5 environment. Asahi's separate Lawrence, MA Custom Fabrication Division cleanroom — where spool pieces are welded, cleaned, and bagged — is ISO 6/Class 1000. PP-Pure and PolyPure share the same high-purity piping family. There's also a documented 2015 installation where Chem Proline (Advanced PE) spool pieces replaced failing CPVC in 50% caustic service for a semiconductor OEM. See LibertyCES's semiconductor & high-purity manufacturing page for the full manufacturer cluster.
Named Specifically for SX-EW and Concentrated Acid Service
Asahi/America names Type-21 ball, Type-14 diaphragm, and globe valves specifically for solvent extraction and electrowinning (SX-EW) service, and Type-75/PDCPD butterfly valves for pregnant leach solution (PLS) collection piping. For concentrated sulfuric acid above 95%, Asahi's own published field case stepped up from its flagship Chem Proline Advanced PE piping to Ultra Proline (ECTFE/Halar) single wall or DuoPro (Halar × polypropylene) double wall — a real, vendor-self-selected material escalation, not a generic recommendation.
