Butterfly valve

with handwheelpneumaticelectric

Reliable, flow-optimised and robust. They are available with or without a hand wheel, with an electric actuator, with a stem extension set with or without a position indicator as well as with a hydraulic or pneumatic rotary actuator – the Dueker butterfly valve. Whichever variant you choose, it will be made of ductile cast iron and fully enamelled according to the requirements of DEV (German Enamellers’ Association) guidelines and ISO 11177. This signifies top quality and a long service life – it functions reliably, can withstand a lot and is incredibly versatile. The advantages of Dueker butterfly valves.Hygienic and consistently reliable. Many thousands of kilometres of pipelines carry drinking water to consumers in every country. Hygiene is the ultimate requirement. Long-term functional reliability and load-bearing capacity are a must. As are resistance to ground movements and corrosion protection against environmental conditions. And in all these areas, Dueker valves – made of enamelled ductile cast iron – are unbeatable. And other aspects also come into play and are becoming increasingly important: cost-effectiveness and 100% recyclability – the butterfly valves can simply be melted down again if they should ever need to be. That is what we mean by recycling economy. . Areas of application.For (almost) every scenario. Valves are required for all pipelines that carry liquids in order to shut them off safely. The Dueker butterfly valve closes tightly in both flow directions and can be installed anywhere along the pipe.
