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 screws 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.

3.4 Description
The GEMÜ B52 3-piece 2/2-way metal ball valve is motorized.
It has a plastic actuator housing. A manual override and an
optical position indicator are integrated as standard. The seat
seal is made of PTFE.
3.5 Function
The product is made from stainless steel and has an actuator
flange and a low maintenance electric actuator with a power-
ful DC motor.
The reduction gear in the motor, consisting of a threaded
spindle with a lever, provides the rotation through 90°.
The actuator has an optical position indicator and a manual
override as standard.
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.

Installing the RFID chip
In the corresponding design with CONEXO, this product has
an RFID chip (1) for electronic recognition. The position of the
RFID chip can be seen below.

5 Correct use
Ball valves are used to isolate media flows.
Only clean, liquid or gaseous media must be used, and the
body and seal materials used must be resistant to and suit-
able for this. Contaminated media and / or applications out-
side of the pressure and temperature data may lead to dam-
age to the body and, in particular, to the seals on the ball
valve.
The "Technical data" chapter describes the permissible pres-
sure / temperature range for these ball valves.
DANGER
Danger of explosion!
▶Risk of severe injury or death.
●Only versions that have been approved
according to their technical data may
be used in potentially explosive envir-
onments.
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 suitable for installation in piping and for con-
trolling a media flow. The operating conditions according to
the technical data apply to the media to be controlled.
The product is controlled via a motorized actuator.
The product is not intended for use in potentially explosive
areas.
The product must not be exposed to pressure fluctuations. If
the product is to be used with pressure fluctuations, please
contact GEMÜ.
Due to the design, in the open and closed position, a low
volume of medium may be trapped within the ball or between
the ball and the body.
Expansion of the medium due to temperature differences,
change in state or a chemical response may lead to a high
pressure build-up. In order to prevent unacceptable pressure
increases, a special version with pressure-relief hole in the
ball is available on request for this case.
NOTICE
Build-up of lint!
▶For soft-seated ball valves, due to the relative rotations of
the stainless steel ball valve to the seat seal, slight wear
of the PTFE seals must always be anticipated. Despite
this, the safety of the ball valve is not affected by any po-
tential build-up of lint and the seal materials are compli-
ant in accordance with FDA directives.
