Features & Benefits

1. The valve is lined with Fluorinated Ethylene Propylene (FEP) or Perfluoroalkoxy (PFA), providing superior chemical resistance, non-stick properties, and protection against corrosion and abrasion.

2. The FEP/PFA lining offers exceptional protection against corrosive chemicals, making it ideal for aggressive media and harsh environments.

3. The corrosion-resistant lining and durable construction ensure the valve lasts longer, reducing the need for frequent replacements and maintenance.
