Neles™ PB series PFA lined ball valve

Improving the customer process reliability, safety and efficiency


Neles PB series PFA lined ball valve is a full bore design to minimize pressure loss and provide maximum flow capacity. The flow port and internal parts are fully covered with PFA for excellent corrosion resistance.

Benefits and features


  • PFA liner is "locked-in" to body, ball, & stem. Eliminates liner collapse under vacuum.
  • Injection molded PFA lining is free from pinholes, cracks, swelling, and local uneven thickness
  • Excellent corrosion resistance due to PFA lining and TFM seats
  • More economic than a valve made from high-alloy materials
  • Low torque, smaller actuator, cost and weight saving
  • High flow capacity & unrestricted flow
  • Bi-directional bubble tight
  • Easy for actuator automation


  • All wetted surfaces fully coated with PFA
  • 2-piece off-center split body
  • Anti-blowout stem
  • Straight bore design
  • Durable TFM seat, zero leak
  • ISO-5211 mounting pad
