Butterfly control valves Butterfly valves are normally used as shut-off valves in pipeline systems. KIESELMANN offers a cost-effective control valve on the basis of the proven butterfly valves for simple control tasks. These butterfly control valves are available with screw connection or welded design as well as in intermediate flange design which is easy to maintain. In order to adapt the valve to the process, actuations with three different power levels are available. The control possibilities are the same as with single-seat control valves, but they don’t reach the same control accuracy due to the design-related moment of inertia of the sealing washer/flap. The advantages for your plant: ► Cost-effective control valve ► Three actuations with compatible connections PDA 75 / PDA 100 /PDA 125 ► Intermediate flange design easy to maintain
