Installation
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, nominal size, material,
pressure rating and temperature range)
match the plant conditions (nominal size
and pressure rating of the pipeline, me-
dium temperature etc.). See the 'Mark-
ings on the device' chapter for name-
plate details.
− The requested or required additional
pipe ttings (see the 'Additional ttings'
chapter) 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 connections
to ensure they are seated correctly. Com-
ponents may loosen during transport.
5.3 Mounting the device
The activities listed below are necessary to
install the valve and before it can be started
up.
Risk of the process medium being contami-
nated through the use of unsuitable lubri-
cants and/or contaminated tools and com-
ponents.
Î Keep the valve and the tools used free
from solvents and grease.
Î Make sure that only suitable lubricants
are used (see the 'Tightening torques, lu-
bricants and tools' chapter in the Appen-
dix).
Risk of control valve damage due to over-
or under-torquing.
Observe the specied torques when tighten-
ing control valve components. Excessive
tightening torques lead to parts wearing out
more quickly. Parts that are too loose may
cause leakage.
Î Observe the specied tightening torques
(see the 'Tightening torques, lubricants
and tools' chapter in the Appendix).
