Motorized diaphragm valve

  • Description
  • Features
  • Technical specifications

The GEMÜ 649 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 diagnosis purposes.
