- Corrosion resistance: The PTFE lining butterfly valve can effectively resist various corrosive media, such as acids, alkalis, solvents, etc.. The valve can work stably for a long time in harsh working environments.
- Sealing performance: The dual polarization structure ensures excellent sealing ability. It can prevent media leakage and ensure the safe operation of the pipeline system.
- Wear resistance: PTFE lining butterfly valve has excellent wear resistance. The valve has maintain stable performance during long-term use, and reduce the frequency of maintenance and replacement.
- Smooth fluid characteristics: There are no protrusions inside the valve body. when the fluid passes through the valve, little reduces resistance and pressure drop will occur, then it improves work efficiency.
- Light and easy operation: The structure of Double Flanged Butterfly Valve is light and flexible, easy to operate. In other words, it can open and close quickly, reducing the labor intensity of the operator.
- Reliable performance: The PTFE lining butterfly valve is made of high-quality materials and undergoes strict quality control and testing to ensure the valve has reliable performance and long life.
