Rotork electric valve actuators have been installed during a modernisation project at an important hydroelectric generating plant serving the state of Queensland in North East Australia Rotork's Australian subsidiary company at Brisbane supplied 70 AQ range IP68 watertight quarter-turn electric actuators to operate ball valves installed at the Kareeya Hydro on the Tully River as part of a project to automate the hydraulic operating system on the main turbine feeder valves

Next generation for electronic valve actuation
Actuation market leader Rotork announces the introduction of the next generation of intelligent valve actuation.
Situated in an area of tropical rainforest in Northern Queensland, the Kareeya Hydro - which takes its name from the Aboriginal word meaning "big water" - has been generating electricity since 1957.
The 72MW plant plays an important role in meeting Queensland's peak load electricity requirements, whilst its fast response time also contributes to the security of the state's electricity distribution system.
The four 18MW turbo generating sets each consist of two Pelton turbines and a generator.
Water is discharged at high velocity through two nozzles on each turbine, striking wheels equipped with 22 buckets (or 'Pelton runners').
The plant is operated by Stanwell Corp, which has used Rotork valve actuators for a number of years on power industry projects throughout Queensland.
The AQ actuators for Kareeya were supplied by Rotork to Fluid Controls of Brisbane for attachment to the valves.
