Features

  • The perfluoroalkoxy resin-lined assembly provides corrosion protection by shielding metal parts from the process media, making it ideal for controlling severely corrosive media.
  • Because all metal parts are shielded from the process fluid, the use of expensive alloys is not necessary.
  • Lining thickness is a minimum of 5 millimeters at all areas where the valve is exposed to process flow. Transfer molding techniques provide for excellent consistency, density, and low permeability. Transfer molded PFA material is translucent.
  • Greater safety under vacuum and high temperature service is achieved by dovetail anchorings which provide a mechanical bond, minimizing the possibility of detachment of the lining from the cast valve body.
  • The top entry design eases in-line maintenance.
  • The PTFE bellows seal is leak tight and, with proper use and maintenance, can have an expected life cycle exceeding 500,000 full stroke cycles.
