2 Safety information
The safety information in this document refers only to an in-
dividual product. Potentially dangerous conditions can arise
in combination with other plant components, which need to
be considered on the basis of a risk analysis. The operator is
responsible for the production of the risk analysis and for
compliance with the resulting precautionary measures and
regional safety regulations.
The document contains fundamental safety information that
must be observed during commissioning, operation and
maintenance. Non-compliance with these instructions may
cause:
– Personal hazard due to electrical, mechanical and
chemical effects.
– Hazard to nearby equipment.
– Failure of important functions.
– Hazard to the environment due to the leakage of dan-
gerous materials.
The safety information does not take into account:
– Unexpected incidents and events, which may occur
during installation, operation and maintenance.
– Local safety regulations which must be adhered to by
the operator and by any additional installation person-
nel.
Prior to commissioning:
1. Transport and store the product correctly.
2. Do not paint the bolts and plastic parts of the product.
3. Carry out installation and commissioning using trained
personnel.
4. Provide adequate training for installation and operating
personnel.
5. Ensure that the contents of the document have been fully
understood by the responsible personnel.
6. Define the areas of responsibility.
7. Observe the safety data sheets.
8. Observe the safety regulations for the media used.
During operation:
9. Keep this document available at the place of use.
10. Observe the safety information.
11. Operate the product in accordance with this document.
12. Operate the product in accordance with the specifica-
tions.
13. Maintain the product correctly.
14. Do not carry out any maintenance work and repairs not
described in this document without consulting the manu-
facturer first.
In cases of uncertainty:
15. Consult the nearest GEMÜ sales office.

3.4 Description
The GEMÜ R649 2/2-way diaphragm valve has a hollow shaft
actuator and is electrically operated. The eSyDrive hollow
shaft actuator can be operated as an ON/OFF actuator or as
an actuator with integrated positioner or process controller.
An integral optical and electrical position indicator is stand-
ard.
3.5 Function
The product controls or regulates (depending on version) a
flowing medium by being closed or opened by a motorized
actuator.
The product has an optical position indicator as standard.
The optical position indicator indicates the OPEN and
CLOSED positions.

The Kv values for other product configurations (e.g. other diaphragm or body materials) may dif-
fer. In general, all diaphragms are subject to the influences of pressure, temperature, the process
and their tightening torques. Therefore the Kv values may exceed the tolerance limits of the stand-
ard.
