Digital valve controllers can provide diagnostic data about the valve assembly. But how many users can correctly interpret the data they get? Are they getting understandable messages or confusing graphs and status bits that leave it unclear if something needs to be done immediately or during the next shutdown? And how about the emergency shutdown valve – is the safety action available? Valve controller vendors have different approaches on how to present the available data. Not all are really turning this data into information that delivers the message to the users. Of course, training can help to interpret the data, but in case special know-how is needed, the number of capable people will be limited to the trained specialists. Do they have time when a shutdown is planned – or is the specialist available if a problem arises late on a Saturday evening?
The Metso product family of digital valve controllers has been among those with state-of-the-art diagnostics for almost two decades. The amount of available data has been huge from the very beginning, so the latest developments have aimed to make all the data easy to use or even intuitive. This means packaging the data as information in a single view that makes the user pay attention to the right things, guide him/her to more information and provide easy guidelines for checking and corrective actions. This easy-to-use diagnostics is available for control valves, on-off valves and emergency shutdown valves, on top of a Metso actuator or any 3rd party actuator.
