The GEMU 618 2/2-way diaphragm valve has a low maintenance motorized actuator with a reversible synchronous motor. Operation takes place via a non-self-locking reduction gear and cam. An integral optical position indicator is standard. The 618 is also available without a metal distance piece for applications with lower operating temperatures (only diaphragm size 10).
Features
- Suitable for inert and corrosive liquid and gaseous media
- Insensitive to particulate media
- The motor will withstand being stalled under full voltage
- Valve body and diaphragm available in various materials and designs
- Suitable for use as a control valve (with integrated control module)
Advantages
- Direct 0/4 – 20 mA signal processing (with integrated control module)
- Opening and closing behaviour is independent of the operating pressure
- Hermetic separation between medium and actuator
- Optional flow direction
- Installation for an optimized draining is possible
