Malfunctions

8.2 

Emergency action

Plant operators are responsible for emergen-
cy action to be taken in the plant.
In the event of a valve malfunction:
1.  Close the shut-off valves upstream and 

downstream of the control valve to stop 
the process medium from flowing 
through the valve.

2.  Perform troubleshooting (see sec-

tion 8.1).

3.  Rectify those malfunctions that can be 

remedied based on the instructions pro-
vided here. Contact our after-sales ser-
vice in all other cases.

Putting the valve back into operation after 

a malfunction

See the 'Start-up' section.
