WARNING!
For maintenance work on the valve, make
sure the relevant section of the pipeline is
depressurized and, depending on the pro-
cess medium, drained as well.
For high medium temperatures, allow the
section of the pipeline to cool down before
you start.
Make sure the control signal for the actuator
is switched off.
The control valve is subject to natural wear.
Depending on the conditions the valve is op-
erated in, it needs to be checked at regular
intervals.
If leakage to the atmosphere occurs, disas-
semble the valve and replace the damaged
parts.
