Global actuation manufacturer, Rotork, has recently installed over 700 CK modular electric actuators at the Shantou wastewater treatment in Guangdong, southern China facilities, where they enable sewage treatment to be carried out in accordance with new environmental regulations.
The CK actuators were selected due to their performance and economical price reliability. Rotork Site Services were able to have the actuators commissioned within the tight timeframe specified for this project and will continue to provide maintenance services following the installation. Rotork’s CK range of actuators is ideal for valves in the water industry and the modular nature of the actuators means that they can be configured to meet the needs of many different applications. With a multi-turn output torque of up to 10,800 Nm (8,000 lbf.ft), these actuators can provide continuous valve position indication, even on loss of power.
In order to comply with the new environmental regulations, three new sewage treatment plants and 300 sewage intercepting wells will be built. The installation of the CK actuators was a critical part of this enhancement. They have been installed on gate valves around the new sewage treatment plants, where they will be controlling the flow of raw sewage in and out of the sewage interceptors, where contaminants are separated from the wastewater.
