DESIGN&FEATURES
| 1.Zero dead corner is a critical sanitary design for pharmaceutical/food valves, achieved via 3 key controls:
One-piece casting eliminates welds/joints that cause dead corners; Precision CNC machining ensures smooth, continuous inner contours with no recesses/protrusions; Custom-machined diaphragm and valve seat form a seamless fit, with no gaps for medium retention. |
| 2. All the valve's body need to be electrolyzed |
| 3. Achieving Ra ≤ 0.4 μm mirror polish relies on precision electrolytic polishing + fine mechanical grinding, with strict dimensional control and surface defect inspection throughout the process., Double layer membrane: PTFE+EPDM(Working Temperature: -20°C to 150°C) |
