Concentric butterfly valve for drinking water and neutral liquids to max. 70°C

AVK fixed liner, concentric butterfly valves feature an outstanding seating concept with the rubber injection moulded directly on the valve body forming a permanent bond. This eliminates the risk of deformation or dislocation of the liner making the valves suitable under vacuum conditions. The combination of the profiled disc edge and the excellent AVK rubber quality ensures maximum durability of the liner.
