  • PFA lining offers highest corrosion resistance
  • Bubble tight shut-off: precision machined ball and seats ´┐Żguarantees an absolute leak-free valve.
  • Full bore offers high Kv-value equal to the pipe
  • One-piece ball/stem: no possibility of damaging PFA-lining on ball by the stem, no hysteresis, ideal for flow control applications.
  • Specific anti blow-out shaft design, which can not be affected by the media, according API 609.
  • Static electricity: any build-up of static electricity is ´┐Żeliminated since the ball/stem and the housing are of the same potential.
  • Constant torque: the unique two-piece body construction together with the spring loaded seats guarantee a constant torque even after months of operation. TA-Luft VDI 2440 approved.
  • The self adjusting packing is maintenance free and provides a leak free stem seal.
  • The handlever features a positive locked position in the open and closed position for type NTB, and 6 intermediate positions for type NTC.
  • The body has a thermally applied polyester powder coating (RAL 9002) which offers excellent protection against external corrosion and rust.
  • Direct mounting according to ISO 5211.
