2/2-way butterfly valve in metal for shutting off and controlling media flows. Based on the fact that the butterfly valve is available in various designs (intermediate flange, end flange) and in different materials, it meets the requirements of various applications and processes. Preferential areas of application for butterfly valves are, for example, the metal industry, power plant technology, paper industry as well as mining, shipbuilding and mechanical engineering. Further characteristics and advantages are: • Through shaft for self-centering disc --> even wear and low torque • PFA-coated shaft in the sealed area • Blow-out proof shaft seal • Spherically shaped disc • Notched handle in ductile iron: lockable in 10 adjustable positions
