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
substances.
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.
14. Do not carry out any maintenance work and repairs not de-
scribed in this document without consulting the manufac-
turer first.
In cases of uncertainty:
15. Consult the nearest GEMÜ sales office.

3.2 Description
The GEMÜ R629 eSyLite 2/2-way diaphragm valve is motor-
ized. It is available in an Open/Closed version. An integrated
optical position indicator is standard. The self-locking actu-
ator holds its position in a stable manner in the event of
power supply failure.

4 Correct use
3.3 Function
The product controls a flowing medium by being closed or
opened by a motorised actuator. The product is designed as
an OPEN/CLOSED valve and is not intended for control applic-
ations.
The product has an optical position indicator as standard. The
optical position indicator indicates the OPEN and CLOSED po-
sitions.
3.4 Product label
The product label is located on the actuator. Product label
data (example):
Design in accordance with order data
Device-specific data
Year of manufacture
Item number Traceability number Consecutive number
The month of manufacture is encoded in the traceability num-
ber and can be obtained from GEMÜ. The product was manu-
factured in Germany.
The operating pressure stated on the product label applies to
a media temperature of 20 °C. The product can be used up to
the maximum stated media temperature. You can find the
pressure/temperature correlation in the technical data.
4 Correct use
DANGER
Danger of explosion!
▶Risk of death or severe injury
●Do not use the product in potentially
explosive zones.
WARNING
Improper use of the product!
▶Risk of severe injury or death
▶Manufacturer liability and guarantee will be void.
●Only use the product in accordance with the operating
conditions specified in the contract documentation and in
this document.
The product is designed for installation in piping systems and
for controlling a working medium.
The product is not intended for use in potentially explosive
areas.
1. Use the product in accordance with the technical data.
2. The product is designed as an OPEN/CLOSED valve and is

6.1 Medium
Working medium: Corrosive, inert, gaseous and liquid media which have no negative impact on the physical and
chemical properties of the body and diaphragm material.
The valve will seal in both flow directions up to full operating pressure (gauge pressure).

If the emergency power module is used (control module code A1, A2, Z1, Z2), the maximum ambi-
ent temperature is reduced to 40 °C.
Storage temperature: 0 — 40 °C
6.3 Pressure
Operating pressure: 0 — 6 bar
All pressures are gauge pressures. Operating pressure values were determined with static operating pressure
applied on one side of a closed valve. Sealing at the valve seat and atmospheric sealing 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.

Data for extended temperature ranges on request. Please note that the ambient temperature and media temper-
ature generate a combined temperature at the valve body which must not exceed the above values.

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 dur-
ation of use.
