Flanged Ends AKH2.2

The ATOMAC full port AKH2.2 lined ball valve has the same characteristics as the AKH2 however the AKH2.2 offers enhanced features to improve suitability for toxic and corrosive applications.

The FLOWSERVE AKH2.2 design features a static and dynamic middle flange seal and in comparison with the AKH2 the metal-to-metal body joint which protects this seal. The metal-to-metal body joint absorbs destructive pipe vibrations and distortions so that there will be no negative effects on the sealing performance. Thermal cycling does not require retightening of the bolts anymore. The packing is constantly preloaded through a set of belleville washers retained within a top cap. The packing is maintenance free and meets environmental standards such as TA Luft.

The top cap also provides the actuator mounting platform per ISO 5211. Seats have a larger diameter and therefore create less flow turbulences across the seat area and the integral retention lip cares for extra seat stability. Also available with FEP, PFA, Tefzel, PP, PVDF and PFA-conductive liner materials as well with a V-ball for precise modulating control service or with C-ball available.
