Operation; Control Functions - Gemu 605 Installation, Operating And Maintenance Instruction

Installation:
1. Ensure the suitability of the valve for
each respective use. The valve must
be appropriate for the piping system
operating conditions (medium, medium
concentration, temperature and
pressure) and the prevailing ambient
conditions. Check the technical data of
the valve and the materials.
2. Shut off plant or plant component.
3. Secure against recommissioning.
4. Depressurize the plant or plant
component.
5. Completely drain the plant (or plant
component) and let it cool down until
the temperature is below the media
vaporization temperature and scalding
can be ruled out.
6. Correctly decontaminate, rinse and
ventilate the plant or plant component.
Installation - Butt weld spigots:
1. Adhere to good welding practices!
2. Disassemble the actuator with the
diaphragm before welding the valve
body into the pipeline (see chapter 11.1).
3. Allow butt weld spigots to cool down.
4. Reassemble the valve body and the
actuator with diaphragm (see chapter
11.4).
Installation - Clamp connections:
When assembling clamp connections,
G
insert a gasket between the body clamp
and the adjacent piping clamp and join
them using the appropriate clamp fi tting.
The gasket and the clamp for clamp
connections are not included in the scope
of delivery.
Important:
Butt weld spigots /
Clamp connections:
Angle of rotation for welding into
pipeline to enable optimised
draining see brochure "Angle of
rotation" (on request or
www.gemu-group.com).

Installation - Threaded connections:
Screw the threaded connections into
G
the piping in accordance with valid
standards.
Screw the diaphragm valve body into the
G
piping, use appropriate thread sealant.
The thread sealant is not included in the
scope of delivery.
Observe appropriate regulations
for connections!
After the installation:
Reactivate all safety and protective
G
devices.

Control functions

The following control functions are available:
Control function 1
Normally closed (NC):
Valve resting position: closed by
spring force. Activation of the actuator
(connector 2) opens the valve.
When the actuator is vented, the
valve is closed by spring force.
