Real Specifications
| Type-57 LIS pressure/temp | 150 psi @ 70°F | asahi-america-metal-replacement-valves.md |
| Type-57 LIS shutoff class | Class 6 bubble-tight shutoff | asahi-america-metal-replacement-valves.md |
| Type-57 LIS stem/seat isolation | Non-wetted 316SS stem fully engaged over the disc length and isolated from media; full seat design isolates body/stem from media | asahi-america-metal-replacement-valves.md |
Semiconductor is one of the industries this family is explicitly named for, and the Type-57 LIS's full-seat isolation — keeping the stem out of contact with process media entirely — is the real reason it belongs on a fab's wet-chlorine or acid-waste line, not just its bubble-tight shutoff class.
