2 Safety information
The safety information in this document refers only to an indi-
vidual 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 re-
sponsible for the production of the risk analysis and for com-
pliance with the resulting precautionary measures and re-
gional safety regulations.
The document contains fundamental safety information that
must be observed during commissioning, operation and main-
tenance. 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 dangerous
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 personnel.
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 specifications.
13. Maintain the product correctly.

3.2 Description
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 per-
formance and a long service life. In addition to OPEN/CLOSE
applications, the valve is ideal for variable and complex con-
trol applications. The actuator has an integrated web server
for parameterization and diagnosis purposes.
3.3 Function
The product controls or regulates (depending on version) a
flowing medium by being closed or opened by a motorized ac-
tuator.
The product has an optical position indicator as standard. The
optical position indicator indicates the OPEN and CLOSED po-
sitions.

The sterilization temperature is only valid for steam (saturated steam) or superheated water.
If the sterilization temperatures listed above are applied to the EPDM diaphragms for longer periods of time, the
service life of the diaphragms will be reduced. In these cases, maintenance cycles must be adapted accord-
ingly.
PTFE diaphragms can also be used as moisture barriers; however, this will reduce their service life. This also ap-
plies to PTFE diaphragms exposed to high temperature fluctuations. The maintenance cycles must be adapted
accordingly. GEMÜ 555 and 505 globe valves are particularly suitable for use in the area of steam generation
and distribution. The following valve arrangement for interfaces between steam pipes and process pipes has
proven itself over time: A globe valve for shutting off steam pipes and a diaphragm valve as an interface to the
process pipes.

8.6.5 Communication
Interface: Ethernet
Function: Parameterisation via web browser
IP address: 192.168.2.1 alterable via web browser
Subnet screen: 255.255.252.0 alterable via web browser
The actuator and the PC must be in the same network to use the web server. The IP address of the actuator is entered in the
web browser and the actuator can then be parametrised. In order to use more than one actuator, a definitive IP address must be
assigned to each actuator in the same network.
