Installation
Pipeline routing
To ensure that the valve functions properly,
proceed as follows:
Î Do not exceed the maximum permissible
ow velocity.
The plant operator is responsible for deter-
mining the maximum permissible ow veloci-
ty. Our after-sales service can support you to
determine the ow velocity for your plant.
Î Install the valve free of stress and with the
least amount of vibrations as possible.
Read information under “Mounting posi-
tion” and “Support or suspension” in this
section.
Î Install the valve allowing sufcient space
to remove the actuator and valve or to
perform service work on them.
Support or suspension
The plant engineering company is responsi-
ble for selecting and implementing a suitable
support or suspension of the installed control
valve and the pipeline.
Depending on the valve version and mount-
ing position, the valve, actuator and pipeline
must be supported or suspended.
5.2 Preparation for installation
Before installation, make sure the following
conditions are met:
− The valve is clean.
− The valve and all valve accessories (in-
cluding piping) are not damaged.
− The valve data on the nameplate (type
designation, valve size, material, pres-
sure rating and temperature range)
match the plant conditions (size and
pressure rating of the pipeline, medium
temperature etc.). See the 'Markings on
the device' section for nameplate details.
− The requested or required additional
pipe ttings (see the 'Additional ttings'
section) have been installed or prepared
as necessary before installing the valve.
Proceed as follows:
Î Lay out the necessary material and tools
to have them ready during installation
work.
Î Flush the pipelines.
The plant operator is responsible for clean-
ing the pipelines in the plant.
Î For steam applications, dry the pipelines.
Moisture will damage the inside of the
valve.
Î Check any mounted pressure gauges to
make sure they function properly.
Î When the valve and actuator are al-
ready assembled, check the bolted joints.
Components may loosen during trans-
port.
