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
Diaphragm valve GEMÜ 650TL is a manually operated dia-
phragm valve with a pneumatic fail safe function. The valve
can only be operated manually (opened/closed) if the actu-
3 Product description

www.gemu-group.com6 / 42GEMÜ 650TL
4 GEMÜ CONEXO
ator is supplied with compressed air. If this supply is interrup-
ted, the valve closes due to the force of the spring and can no
longer be opened manually.
3.3 Function
The closed position feedback of pneumatic piston and hand-
wheel takes place via flush mountable proximity switches (op-
tional). The valve has CIP/SIP cleaning and sterilizing capabil-
ities.
3.4 Control function
The following control functions are available:
Control function 1: Normally closed (NC)
3.5 Optical position indicator
The product has an optical position indicator as standard. The
optical position indicator indicates the OPEN and CLOSED po-
sitions.

GEMÜ 650 1TL/650 2TL

* Only if control medium has been applied to the actuator and
the manual actuator has been put in the OPEN position.
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.

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.
Control medium: Inert gases
7.2 Temperature
Media temperature: -10 — 100 °C
For special function S: 0 — 60 °C
Sterilization temperature: EPDM (code 3A/13) max. 150 °C, max. 60 min per cycle
EPDM (code 17) max. 150 °C, max. 180 min per cycle
EPDM (code 19) max. 150 °C, max. 180 min per cycle
PTFE/EPDM (code 54) max. 150 °C, constant temperature per cycle
PTFE/EPDM (code 5M) max. 150 °C, constant temperature per cycle
The sterilization temperature is only valid for steam (saturated steam) or superheated water.
If the sterilization temperatures listed above are applied to the EPDM diaphragms for longer periods of time, the
service life of the diaphragms will be reduced. In these cases, maintenance cycles must be adapted accord-
ingly.
PTFE diaphragms can also be used as steam barriers; however, this will reduce their service life. This also ap-
plies to PTFE diaphragms exposed to high temperature fluctuations. The maintenance cycles must be adapted
accordingly. GEMÜ 555 and 505 globe valves are particularly suitable for use in the area of steam generation
and distribution. The following valve arrangement for interfaces between steam pipes and process pipes has
proven itself over time: A globe valve for shutting off steam pipes and a diaphragm valve as an interface to the
process pipes.

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.
