Butterfly valves

Keulahütte’s product portfolio is rounded off with a range of butterfly valves that are available in nominal diameters ranging from DN 200 to DN 1400 and swing check valves in sizes from DN 80 to DN 300, all made of ductile cast iron.
The valve discs have been developed on the basis of long-standing experience and extensive endurance tests to ensure longevity as well as excellent actuation and flow characteristics.
Combined with suitable drives and encoders, our butterfly valves can be used in electronically monitored and controlled plants and serve as safety elements after power failure. Installation in manholes or buried installation is possible thanks to special sealing elements.
