Selecting the correct butterfly valve is crucial for system performance and longevity. Here are the key factors to consider.

1. Material Selection

Common materials include ductile iron, stainless steel (304/316), and bronze. Choose based on corrosion resistance and working environment.

2. Pressure and Temperature

Always verify the valve rating to ensure it meets your system requirements.

3. Connection Type

  • Wafer – cost-effective
  • Lug – easy maintenance
  • Flanged – high stability

4. Sealing Type

Soft seal (EPDM/PTFE) vs metal seal depends on temperature and media.

5. Application Scenario

Marine, industrial, or chemical applications require different specifications.

Conclusion

Choosing the right butterfly valve improves efficiency and reduces maintenance costs. Always consult with a professional supplier.
