Shut-off valves

For large pipework dimensions, our butterfly valves offer you a reliable solution for the safe control of liquids and gases. With the right combination of materials, they not only ensure efficient handling of mechanically pure liquids, but also of slightly abrasive media - for maximum process reliability and durability.
Various GEMÜ butterfly valves, manual and automated.

Key features

  • Wide range of nominal widths: Offers maximum flexibility for a wide variety of pipe sizes.
  • Very short overall length: Saves space and facilitates integration into compact systems.
  • Fast positioning times: Enable fast reaction times and increase process dynamics.
  • Simple installation and low maintenance: Reduce downtimes and lower operating costs.
  • Typical operation media: Liquids such as water, oils, acids, alkalis, surfactants, heating and cooling agents, Gases such as steam, air, nitrogen, natural gas, noble gases, vapours, Solids such as bulk material
