5.3 Mounting the device

The activities listed below are necessary to
install the valve and before it can be started
up.
NOTICE
!
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.
Î Observe the specified tightening torques
(see 'Tightening torques' in Annex).
NOTICE
!
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).
NOTICE
!
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.
