Rotork installed its CK actuators at a Chinese sewage treatment plant

The Guangdong Panyu Sewage Treatment Plant in China has installed Rotork CK Range electric valve actuators to provide reliable and economical plant automation encompassing isolating and modulating valve control, the British actuator company reported in a statement.
The CK actuator design has enabled the plant to use a combination of CK Standard and CK Centronik actuators to automate 89 gate valves and sluices to control the flow throughout the waste water treatment process.
Standard features that are common to all CK actuators include IP68 double-sealed environmental protection, plug and socket connections for fast and efficient commissioning and maintenance, motor-independent handwheel operation, mechanical valve position indication and independent torque and position sensing for increased valve protection. Actuator gearboxes are oil lubricated for extended life and separable thrust or non-thrust bases enable actuators to be removed without disturbing the valve position.
