The KTN AP11N is our version of the jacketed lug ball valve for extreme services, offering absolute tightness while allowing sudden changes in temperature (-46ºC – + 400ºC), high pressures and media with abrasive solids.

All this thanks to the use of its pentaphite seats, a self-lubricating metallic component whose metallic properties offer great compression capacity and resistance to corrosion, its high elasticity, on the other hand, allows it to adapt to the sphere, avoiding displacement of the seat, reducing the torque and obtaining a total tightness.
