The GEMÜ 649 eSyDrive diaphragm valve is actuated by a motorized hollow shaft actuator. It is based on technology that does not use brushes or sensors and therefore guarantees high performance and a long service life. In addition to Open/Close applications, the valve is ideal for variable and complex control applications. The actuator has an integrated web server for parameterization and diagnostics purposes.

  • Open/Close function, positioner and process controller
  • Force and speed are variably adjustable
  • Extensive diagnostic functions
  • Operable via web interface eSy-Web or Modbus TCP
  • Hollow shaft drive based on brushless and sensorless technology
  • Various functions of add-on components and accessories are already integrated (e.g. position indicators, stroke limiters, etc.)
  • Hermetic separation between medium and actuator
