7.4 Service Function
If maintenance must be conducted on a process valve that is fitted with a control
top T.VIS M-15, the valve core must be pulled out of the housing. For this
purpose, the valve disk pretension of the process valve must be relieved by
actuating the main actuator. This is possible with the service function, see
“Operating overview” .
Another option with the hood removed is the manual override on the solenoid
valve, see “Control top with solenoid valves” .
