Cast iron lug butterfly valve

XUVAL centric butterfly valves with fixed liner feature an outstanding seating concept. The rubber is injection molded directly on the valve body forming a permanent bond. Consequently, there is no 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 XUVAL rubber quality ensures maximum durability of the liner.
