AS PART OF A PROJECT TO automate the hydraulic operating system on the main turbine feeder valves at the Kareeya hydro plant in northern Queensland, 70 Rotork valve actuators have been installed.
Rotork's Australian subsidiary in Brisbane supplied the AQ range IP68 watertight, quarter- turn electric actuators during a modernisation programme.
The Kareeya plant, which takes its name from the Aboriginal word meaning big water, has been generating electricity since 1957. The plant has 4x18MW Pelton turbines and plays an important role in meeting Queensland's peak load electricity requirements. It is operated by the Stanwell Corporation.
