Model NTB/NTC Lined - Self adjusting stem seal and ideal for corrosive applications

These PFA lined ball valves are used in a wide variety of applications in many industries.

The valves are ideally suited for corrosive applications, requiring reliable performance, tight shutoff, constant torque and no maintenance. The valves successfully handle a multitude of corrosive applications in industries such as chemical, petrochemical, pharmaceutical, pulp and paper, foundries and mining like sulphuric acid, etc. This unique design, together with 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.

Features:

  • 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.
