Asahi's Wet Process Solutions / Dymatrix line is semiconductor-specific and names Diaphragm as one of its valve types; the Custom Fabrication Division's Class 1000 cleanroom (24,000 sq ft fab shop in the 200,000 sq ft Lawrence, MA facility) is the supporting capability. Richter's MV is separately stated cleanroom capable. Moderate because Dymatrix is captured at valve-type-name level with no per-model spec table.

Real Specifications
| Richter MV pressure & temperature | 16/10/7 bar by size, -30°C to +150°C, cleanroom capable | richter-ct-sliding-stem-valves.md |
| Asahi cleanroom capability | Custom Fabrication Division's Class 1000 cleanroom, 24,000 sq ft fab shop within the 200,000 sq ft Lawrence, MA facility | asahi-america.md |
| Dymatrix family split | Semiconductor-critical Dymatrix line vs. a separate 'Industrial Dymatrix' line for less-critical non-semiconductor service | asahi-america.md |
Asahi itself splits its diaphragm valve family into semiconductor-critical Dymatrix and a lower-tier 'Industrial Dymatrix' for less-critical service — a real distinction worth confirming before a fab quote defaults to the less-rigorous line on price alone.

FAQ
Is Diaphragm Valve used in Semiconductor / High Purity?
Asahi's Wet Process Solutions / Dymatrix line is semiconductor-specific and names Diaphragm as one of its valve types; the Custom Fabrication Division's Class 1000 cleanroom (24,000 sq ft fab shop in the 200,000 sq ft Lawrence, MA facility) is the supporting capability. Richter's MV is separately stated cleanroom capable. Moderate because Dymatrix is captured at valve-type-name level with no per-model spec table. This is moderate evidence.
