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 629 eSyLite 2/2-way diaphragm valve is motorized.
It is available as an Open/Close version. An integrated optical
position indicator is standard. The self-locking actuator holds
its position in a stable manner in the event of power supply
failure.
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 GEMÜ CONEXO
The interaction of valve components that are equipped with
RFID chips and an associated IT infrastructure actively in-
crease process reliability.
Thanks to serialization, every valve and every relevant valve
component such as the body, actuator or diaphragm, and
even automation components, can be clearly traced and read
using the CONEXO pen RFID reader. The CONEXO app, which
can be installed on mobile devices, not only facilitates and im-
proves the "installation qualification" process, but also makes
the maintenance process much more transparent and easier
to document. The app actively guides the maintenance techni-
cian through the maintenance schedule and directly provides
him with all the information assigned to the valve, such as
test reports, testing documentation and maintenance histor-
ies. The CONEXO portal acts as a central element, helping to
collect, manage and process all data.

5 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
not intended for control applications. Due to the minimum
actuation time, sufficiently accurate control is not pos-
sible.

7 Technical data
7.1 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).
7.2 Temperature
Media temperature: -10 — 80 °C
Ambient temperature: -10 — 50 °C
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

MG = diaphragm size
Kv values in m³/h
Kv values determined in accordance with DIN EN 60534 standard, inlet pressure 5 bar, Δp 1 bar, stainless steel
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 stand-
ard.
The Kv value curve (Kv value dependent on valve stroke) can vary depending on the diaphragm material and dur-
ation of use.
