Neotecha Model NTB/NTC PFA Lined Ball Valves

Neotecha Model NTB/NTC PFA Lined Ball Valves

NTB/NTC Lined Ball Valves valves are suited for corrosive applications, requiring reliable performance, tight shutoff, constant torque and zero maintenance. These valves handle different corrosive applications in industries such as chemical, petro-chemical, pharmaceutical, pulp and paper, foundries and mining like sulphuric acid, etc. The products' unique design and the self-adjusting stem seal (U.S. Patent 4.696.323) are two of the reasons behind the excellent performance and broad industry acceptance of this valve.

Media Aggressive Liquids/Gases
  • PFA lining offers highest corrosion resistance
  • Bubble tight shut-off: precision machined ball and seats ­guarantees 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 ­eliminated 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.
