Real Specifications
| Spec | Value | Source document |
|---|---|---|
| Type-57 LIS pressure/temp | 150 psi @ 70°F | Asahi/America — Thermoplastic Valves: Direct Replacement for Metal Valves |
| Type-57 LIS shutoff class | Class 6 bubble-tight shutoff | Asahi/America — Thermoplastic Valves: Direct Replacement for Metal Valves |
| 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 — Thermoplastic Valves: Direct Replacement for Metal Valves |
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.
