Control valve
Thread Content
What do the valve fault conditions FLO\FLC of a control valve mean?
It indicates the fault location. FL stands for fault holding position, while FLO means that the valve’s fault location varies depending on the type of fault; for example, in the case of a gas supply fault, the valve remains in its holding position, whereas in the case of a power supply fault, the valve opens fully. Or the other way around. This has been confirmed based on the process conditions.
It is recommended to check the manual and refer to the error code
I’m so envious that you can use intelligent valve positioners
