The manufacturing process of pneumatic control valves includes casting, machining, assembly, testing and other links. Each step needs to be strictly controlled to ensure the quality of the final product.
- Precision casting: Sand casting, investment casting and other technologies are used to ensure the complexity of the valve body shape while achieving high dimensional accuracy and surface finish.
- CNC machining: Computer numerical control machine tools process the internal channels and parts of the valve body to ensure high-precision matching, improve sealing performance and adjustment accuracy.
- Surface treatment: Such as electroplating, painting, passivation treatment, etc., to enhance the corrosion resistance and aesthetics of the valve.
- Assembly and testing: Professional tools and processes are used to ensure the correct assembly of each component. The completed valve must undergo strict airtightness, functionality and performance tests to ensure factory quality.
