CBF01-TF01-Operation and Maintenance Manual DOWNLOAD

1. Superior Corrosion Resistance & Extended Service Life
The Full Stainless Steel Body and Disc construction, typically made from grades like CF8M (316 SS), provides excellent corrosion resistance against acids, alkalis, salts, and various aggressive media.
Stainless Steel Material significantly enhances the valve service life in harsh applications, reducing replacement frequency and total cost of ownership.
2. Double Flanged Robustness
The Double Flanged Connection design ensures a strong, stable mechanical link to the piping system, effectively preventing leaks and withstanding higher pipe stress. 。
This flange structure, combined with high-quality seat materials (like EPDM or PTFE), enables bubble-tight bidirectional sealing, meeting strict safety and environmental standards for high-pressure and high-temperature applications.
3. High Operational Efficiency and Low Maintenance Cost
The inherent butterfly valve design is simple, compact, and allows for quick operation.
The stainless steel disc ensures smooth media flow with a low pressure drop, minimizing energy loss.
Its low operating torque allows for easy manual operation or simple adaptation to pneumatic actuators and electric actuators for automation.
The robust stainless steel construction requires minimal maintenance, drastically reducing long-term maintenance costs.
