Real Specifications
| Type-57 LIS pressure/temp | 150 psi @ 70°F, Class 6 bubble-tight shutoff | asahi-america-metal-replacement-valves.md |
| Type-57 LIS materials | PVC body; PVC/CPVC/PP/PVDF disc; EPDM/FKM/Nitrile seat; 316SS/Titanium/Hastelloy C stem | asahi-america-metal-replacement-valves.md |
| Named landfill process chemistries | Acidic waste, oxidizers, caustics, solvents, halogens named across this family's process-chemistry list | asahi-america-metal-replacement-valves.md |
Landfill leachate is exactly the mixed, unpredictable acidic-waste chemistry this family's process list names — a metal butterfly valve corrodes on leachate collection lines in a way a fully non-metallic-disc Type-57 LIS doesn't, which is the real reason landfills made the vendor's own named-industry list.
