9.1 Periodic testing
Depending on the operating conditions,
check the actuator at certain intervals to pre-
vent possible failure before it can occur.
Plant operators are responsible for drawing
up an inspection and test plan.
Our after-sales service can support you in
drawing up an inspection and test plan for
your plant.
9.2 Preparation for servicing
or conversion work
1. Lay out the necessary material and tools
to have them ready for the intended
work.
2. Put the actuator out of operation (see the
'Decommissioning' section).
3. Remove the actuator from the valve (see
the 'Removal' section).
