PFA Lined CF3M Disc PTFE Lug Butterfly Valve
Features of PFA Lined Lug Butterfly Valve
- PFA-lined cf3m disc: CF3M is equivalent to SS316L, but has enhanced corrosion resistance, making it ideal for highly corrosive environments. So the PFA-lined disc has superior chemical resistance compared to PTFE. It can handle highly corrosive chemicals such as hydrofluoric acid, nitric acid, and strong bases.
- Excellent high temperature performance: PFA material can withstand high temperature environments, ensuring the reliability and performance stability of the valve under high temperature conditions.
- PTFE seat: Well-known as the king of plastics, it provides a non-stick surface and chemical compatibility with a wide range of fluids.
- Simple structure and operation: The PTFE lug butterfly valve adopts a simple structural design. It is easy to operate and does not require complicated maintenance work, and it can reduce 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.
