Woodward Steam Turbine Actuation

    Actuation for Steam Turbine Control Valves

    Woodward steam turbine actuation platforms are designed for low-pressure or high-pressure servo systems and redundancy for high reliability.

    Steam turbine OEMs have long used Woodward steam turbine valve based actuators on their turbine packages due to their high accuracy, fast response times, and long term reliability. Platforms range from self-contained pump/servo systems, to electric actuation, to servo position controllers. These platforms are specifically designed for steam turbine applications and provide proven reliable operation.
