Servicing
(e.g. spring compression). See associat -
ed actuator documentation.
Risk of personal injury due to exhaust air
being vented.
While the valve is operating, air is vented
from the actuator, for example, during
closed-loop operation or when the valve
opens or closes.
Î
Wear eye protection when working in
close proximity to the control valve.
Risk of personal injury due to preloaded
springs.
Actuators with preloaded springs are under
tension. They can be identified by the long
bolts protruding from the bottom of the actu-
ator.
Î
Before starting any work on the actuator,
relieve the compression from the pre-
loaded springs (see associated actuator
documentation).
Risk of personal injury due to residual
process medium in the valve.
While working on the valve, residual me -
dium can flow out of the valve and, depend -
ing on its properties, cause personal injury,
e.g. (chemical) burns.
Î
Wear protective clothing, safety gloves,
respiratory protection and eye protec-
tion.
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
(
u
AB 0100.).
Risk of valve damage due to the use of un-
suitable tools.
Î
Only use tools approved by SAMSON
(
u
AB 0100).
Risk of valve damage due to the use of
unsuitable lubricants.
Î
Only use lubricants approved by
SAMSON (
u
AB 0100).
The control valve was checked by SAMSON
before it left the factory.
− Certain test results certified by SAMSON
lose their validity when the valve is
opened. Such testing includes seat leakage
and leak tests.
− The product warranty becomes void if
service or repair work not described in
these instructions is performed without
prior agreement by SAMSON's After-sales
Service.
