to have them ready during installation
work.
Î
Flush the pipelines.
The plant operator is responsible for clean-
ing the pipelines in the plant.

Moisture will damage the inside of the
valve.
Î
Check any mounted pressure gauges to
make sure they function properly.

5.3 Mounting the device
The activities listed below are necessary to
install the valve and before it can be started
up.
Risk of valve damage due to excessively
high or low tightening torques.
Observe the specified 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.

Observe the specified tightening torques
(see 'Tightening torques' in Annex).
Risk of valve damage due to the use of un-
suitable tools.
Î
Only use tools approved by SAMSON
(see the 'Tools' section in Annex).
Risk of valve damage due to the use of un-
suitable lubricants.
Î
Only use lubricants approved by
SAMSON (see the 'Lubricants' section in
Annex).
Risk of the process medium being contami-
nated through the use of unsuitable lubri-
cants and/or contaminated tools and com-
ponents.
