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 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 specifica-
tions.
13. Maintain the product correctly.

3.3 Description
The GEMÜ R639 is a motorized 2/2-way diaphragm valve.
The eSyStep electric actuator is available as ON/OFF or with
integrated positioner. An integral optical and electrical posi-
tion indicator is standard. The self-locking actuator holds its
position in a stable manner when idle and in the event of
power supply failure.
3.4 Function
The product controls or regulates (depending on version) a
flowing medium by being closed or opened by a motorized
actuator.
The product is equipped as standard with a mechanical posi-
tion indicator as well as an electrical position and status in-
dicator.

All pressures are gauge pressures. Operating pressure values were determined with static operat-
ing pressure applied on one side of a closed valve. Sealing at the valve seat and atmospheric seal-
ing is ensured for the given values.
Information on operating pressures applied on both sides and for high purity media on request.
The operating pressures apply at room temperature. In case of deviating temperatures, observe
the pressure / temperature correlation.

The pressure rating (PN) depends on the connection code.
Data for extended temperature ranges on request. Please note that the ambient temperature and media tem-
perature generate a combined temperature at the valve body which must not exceed the above values.
Depending on the valve configuration, the maximum operating pressure of the pressure rating may be lower.
Observe the operating pressure table.

MG = diaphragm size, Kv values in m³/h
Kv values determined acc.to DIN EN 60534 standard, inlet pressure 5 bar, Δp 1 bar, PVC-U valve body and soft
elastomer diaphragm. The Kv values for other product configurations (e.g. other diaphragm or body materials)
may differ. 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 standard.
The Kv value curve (Kv value dependent on valve stroke) can vary depending on the diaphragm material and
duration of use.
