- Strong corrosion resistance: The PFA lined Disc lug butterfly valve uses PFA lining material, which has excellent corrosion resistance and can safely handle various corrosive media, extending the service life and reliability of the valve.
- Excellent sealing performance: PFA lining has excellent sealing performance, which can effectively prevent media leakage and ensure the safe and stable operation of the pipeline system.
- Excellent high temperature performance: PFA material can withstand high temperature environments, ensuring the reliability and performance stability of the valve under high temperature conditions.
- Simple structure and operation: The PTFE lug butterfly valve adopts a simple structural design, which is easy to operate and does not require complicated maintenance work, reducing maintenance costs and operation difficulty.
- Lug design enables the valve to be installed in a pipeline where one side of the pipeline can be removed without disturbing the other side.This is called dead end service.
- The worm gear transfer rotational motion from a handwheel into linear motion to rotate the PTFE lug butterfly valve disc.
