Surface Treatment
We offer the following processes to choose:
1. Mechanical Polishing (MP) to improve brightness (gloss, matte)
2. Acid Cleaning for Anti-corrosion
3. Electrolysis Polish (EP) to improve surface smoothness
4. Custom Process: Bright Annealing treatment eliminate strees to improve toughness
How do we ensure finished product quality (FQC inspection)
1. Visual Inspection
2. Material Grade Measurement
3. Dimension Inspection
4. Roughness Detection
5. Roughness Detection
6. Leakage Test
Butterfly valves can be actuated either manually or pneumatically. There is a wide range of manual controls to meet the different system requirements. Pneumatic controls can be horizontal and vertical, single-, double-effect, and modulating. They can be fitted with control tops and proximity It is widely applied to many fileds,such as beer,beverage,dairy food,fruit juice,pharmacy,biological etc.
