Decommissioning
Î Before unblocking the actuator stem after
it has become blocked (e.g. due to
seizing up after remaining in the same
position for a long time), release any
stored energy in the actuator (e.g. spring
compression). See 'Relieving the spring
compression in the actuator' in the
'Removal' section.
To decommission the actuator for service
work or before removing it from the valve,
proceed as follows:
1. Put the valve and positioner out of oper-
ation. See associated valve and position-
er documentation.
2. Disconnect the pneumatic air supply to
depressurize the actuator.
