For maximum flexibility, we offer you our between-flange butterfly valves, also with drives in different variants. The butterfly valve with pneumatic drive (image left) is operated with compressed air. These are available in single-acting or double-acting models. Single-acting drives only have one inlet that is operated by compressed air, which opens the valve. It is then closed by a pre-tensioned spring. Double-acting drives have two inlets, one serves to close the valve and the other to open the valve, depending on which inlet is actuated with compressed air. The pneumatic drive can be operated via a Namur valve . We are able to offer the butterfly valves with electric rotary drive (image right) with voltages 24 Volt AC/DC or 230 Volt AC. The electric drive includes a temperature monitor, which constantly monitors the temperature of the motor. Please note that our automated butterfly valves only up to DN400 are available in the webshop. Butterfly valves with larger nominal widths have to be ordered from us. Our motorised butterfly widths are frequently used in water and drinking water treatment, in shipbuilding, in sewage plants, in various hot water or cold water circuits
Irrespective of the drive technology, our butterfly valves are made from high quality spheroidal graphite cast iron GGG40. Some of the drives are designed with protection class IP67, more information is available in the datasheets.
