Electromotive 2/2-way diaphragm valve with plastic body

GEMÜ R649 eSyDrive

ConfigureTechnical data sheet
Electrically automated diaphragm valve with position feedback and screw connections – ideal for process automation, water treatment, and chemical process engineering.

Valve with premium actuator for high performance and long service life

Product information

The GEMÜ R649 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.

Key features

  • Hermetic separation between medium and actuator
  • Installation for optimized draining is possible
  • Open/Close function, positioner and process controller
  • Actuation force and actuating speed variably adjustable
  • Operable via web interface eSy-Web and Modbus TCP
  • Extensive functions, such as position feedback, diagnostic functions and opening and closing stroke limitation
