Stampa la paginaIf a valve has to be removed from a pipeline:
Medium may escape from the line or the valve. In the case of media which are
harmful to health or hazardous the pipeline has to be completely empty before the
valve is removed. Please be careful with residues which continue to flow from
dead spaces of the valve or line or which remain in the valve (under pressure).
Depending on the length of the valve, the disc of the opened valve extends into the

bordering pipeline. As a security measure, the QUADAX valve with actuator should be
removed from the pipeline in the closed position. A disc which is not held by the
actuator may unintentionally open and thus lead to damages or injuries.
2.4 Labeling of the butterfly valve
Each butterfly valve is labeled with the following data (type plate):
Manufacturer
www.co-ax.com
Type code
e.g.:EQK102004XXXXXXXXX
XXX XXC XXXXX
Serial number
e.g.: 251896.1-AA
KNA-Nr.
e.g.: 800005
Type / PN
QUADAX DNXXX (X")
PN / class
Numerical value for PN /
class
CWP / PS
Numerical value in bar or
PSI
max. T / TS
Numerical value in °C or °F
Year of
e.g.: 43/09
manufacture
0036
directional
arrow
The materials used in the valve, as well as parts that come into contact with the media, as
well as pressure parts are uniquely coded in the type code. The manufacturing date can be
uniquely traced via the serial number. In order to be able to identify the valve, the type plate
may not be removed nor damaged.
3 Transport and storage
Valves have to be handled, transported and stored with care:
The valve is to be kept in its original packaging and/or with the protection caps on the
flange connections/weld ends. The valve should be stored and transported (also to
the installation site) on a pallet (or supported in a similar way).
If stored prior to installation, valve and actuator are to be stored in a closed room and
to be protected against harmful influences such as dirt or moisture.
Especially the actuator and the flange connection faces/weld ends must not be
damaged by mechanical or any other influences.
Valves must be stored in the same way they were delivered. The actuator may not be
activated.
Values delivered without an actuator:
The valve must be transported carefully: The unsecured valve disc may open from
closing position due to external effects (e.g shaking).
