Rotork actuators in Chinese water project

21 July 2008

The Dahuofang Water Supply Project, in China, will use over 140 Rotork IQPro actuators to take water from the high rainfall area of Dahuofang Reservoir down to six cities in Liaoning Province.

The electric valve actuators will be a part of the project that incorporates a 231km pipeline, one pump station, six water distribution stations and a buffer tower.

The actuators, with Rotork secondary gearboxes, have been ordered, mostly to operate pipeline and pump station butterfly valves manufactured by German and Chinese valvemakers. Some of the IQPro actuators are modulating versions for control valve duties at the pipeline distribution stations. All of the Rotork actuators are Modbus-enabled to suit the digital bus control protocol selected for the extensive pipeline network.

A water supply tunnel, with a length of 85.3 km, will supersede the 54 km Seikan Rail Tunnel in Japan as the world’s longest when completed.
