Steam turbine control system for increased performance

Simplicity and integration

The Valmet DNA Steam Turbine Automation system offers convenience and simplicity together with the thoroughness of a fully integrated system. It also provides protection and condition monitoring, along with precise turbine control.

With turbine controls, protection and scalable information management all combined in a single Valmet DNA automation package, the system gets machines back up and running quickly. The open-platform solution provides deeper insight into a steam turbine.
