Marking and identification
The valve specifications are placed on the identification
plate.
For maintenance and/or repair, the unique number
(Unique-No) is needed to identify the valve
This number is also engraved in the valve body, so you can
find it even if it cannot be easily detected from the Identifi-
cation plate.
Further information:
Job-No
= Job number of Metso
Unique-No
= Serial number of the valve
Type
= Type code of the valve
Body
= Body material
YEAR
= Year of manufacture
NPS or DN
= Size; CL or PN = Pressure class
ID-No.
= Customer identification number
Tag-No
= Valve number
TS.
= Valve max. working temperature
in °C (medium)
PS
= Valve max. design pressure at max. temp
P.O.NO.
= Customer’s order number / commission
number
Cv
= Flow rate in gal/min
EX II 2GcTx
= ATEX-marking
CE
= CE0036 (notified body for PED)
To display the trim in the built-in condition of the valve, you
will find the following markings (see Fig. 4):
Fig. 4
Identification plate
□
Colored marking on the shaft.
If colored markings on shaft in direction of flow are aligned,
the valve is "CLOSED". The sealing element is located on the
side of the body where you see the colored marking.
Open and close like a tap. (seen from the actuator side).
1.7
ATEX, ASME & CE-marking
The valve meets the requirements of the European Direc-
tive
2014/68/EU
relating to pressure equipment and the
ASME
B 16.34-2009, and has been marked in accordance
with
these directives.
The ATEX, ASME and/or CE markings are placed on the
Identification plate (see Figure 3) in accordance with the
specification of the valve.

Transport, reception and storage
Check the valve – including equipment – for any damage
that may have occurred during transport.
Store the valve carefully before installation, preferably
indoors in a dry place.
Storage temperature = -20° … 80 °C
Humidity 85 % max (non-condensing)
The valve must be stored with the appropriate factory-
made flow port protectors.
The valve is usually delivered in the closed position.
A valve equipped with a spring-return actuator is delivered
in a position determined by the spring. During storage the
valve must be lightly closed.
Transport the valve on-site not until the installation will be
performed.
Remove the flow port protectors before installation.

Installation
Only qualified personnel are permitted to perform
installation work on the valve!
3.1
Installation planning
Before installation, consider the following aspects:
□
Install the valve so that the actuator is easy to access.
□
Do not connect the power supply of the actuator
(electrical, pneumatic or hydraulic energy) until the
installation of the valve is completed.
□
The flange holes of both pipe ends must be exactly
aligned and the sealing surface of the opposing flanges
must be exactly parallel. The flange holes must not be
twisted against each other, to ensure that the installa-
tion cannot cause any stress in the valve. (see Figure 5)
Fig. 5
Check the flange position before installing
3.2
Preliminary
Flush or blow the pipeline carefully before installing the valve.
Foreign particles – such as sand, rust, dirt or welding residues –
will affect the tightness of the valve and damage the disc-seal-
ing surface and seat. This is very important for installation of
valves in new plant sections. Also during this process, the
medium must not carry any contaminant which may settle in
the sealing area.
