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.

3.2 Description
The GEMÜ F60 motorized 2/2-way filling valve is designed
for extremely precise and fast filling processes in aseptic and
hygienic areas of application. GEMÜ F60 enables activation
in real time, ultra-quick load cycles and high flow rates of up
to 6600 litres per hour. The sealing concept of the valve is
based on the GEMÜ PD design, whereby the actuator is her-
metically separated from the medium. All actuator parts (ex-
cept the seals) are made from stainless steel.
3.3 Function
The product is an electrically operated 2/2-way filling valve
made of stainless steel. The GEMÜ F60 2/2-way filling valve
is designed for use in piping systems. The product is non-
self-locking and can be easily moved without force when de-
energized. External leak tightness is nevertheless ensured.
An external controller is required to operate the valve. The
valve does not work without a controller.
With this external controller, the filling valve offers flexible
and fast program changes thanks to freely programmable
filling curves.
The external controller is not included in the scope of deliv-
ery.
