LibertyCES has documented Butterfly Valve in Caustics/Bases service, including Sodium Hydroxide. Wetted materials to confirm: PTFE/PCTFE. Compatibility depends on exact concentration, temperature and duty cycle, so confirm with a free spec review.
Notes from the vendor documentation
NaOH explicitly named; fills gap where Crane's Lined Butterfly Valve (XLD) list omits caustic.

|---|---|---|
| Special Purpose Butterfly Valve named chemistry | Sodium Hydroxide explicitly named in the chemistry-specific application list (Steam, Ore Leaching, Mineral Slurries, Trona Slurry, Hot Acids, Sodium Hydroxide, Chloroform, Chlor-pyridine, Heat Transfer Fluids) | Crane ChemPharma & Energy — XOMOX High Performance Butterfly Valves |
| Seat material options for this family | PTFE/RPTFE (-70°C to +232°C) or Metal-PEEK (-70°C to +260°C) seat options on the same Type 800/800ISO body | Crane ChemPharma & Energy — XOMOX High Performance Butterfly Valves |
Crane's own Lined Butterfly Valve (XLD) family does NOT list sodium hydroxide among its named chemistries — only the Special Purpose Butterfly Valve line does — a real intra-brand gap worth checking before assuming any Crane butterfly valve covers NaOH service.
Sodium hydroxide crystallizes and finds leak paths when it sits somewhere it shouldn't — the reason it's named on Crane's Special Purpose line and not the standard Lined Butterfly family is a real product-line distinction, not an oversight.
Every material and product claim on this page traces to real, vendor-published documentation on file with LibertyCES. Chemical compatibility depends on exact concentration, temperature, and duty cycle — confirm current specifications with the manufacturer and request a spec review before final specification.
