Plant engineers at Eskom’s Majuba Power Station in South Africa have been continuously looking for ways to improve efficiency and reliability. The six-unit, 4,000-MW, supercritical coal-fired plant ...

A single power plant uses hundreds of valves to control almost every aspect of its operation. Valves, in conjunction with a controlling actuator, are used for pollution control, feed water, cooling ...

Copar rotary actuators provide pneumatic control of ball, butterfly, and throttle valves. The challenges of modern process automation are, in a sense, rather basic. Opening, closing, and adjusting ...

The innovative Rotork CK range of modular electric valve actuators has been extended to include a new part-turn variant, known as the CKQ. The entire range has a modular design that provides ...

Moving a load in a straight line can be done using a variety of linear actuator devices employing both rod and rodless technologies. For rod-style actuation requiring lower amounts of force ...

Motors and end effectors come in many shapes and sizes but, compared to actuators that focus on position control, end effectors commonly also integrate force sensing to ensure that objects being ...

Active flow control using plasma actuators offers a novel and increasingly influential method for manipulating aerodynamic flows. By utilising the dielectric barrier discharge mechanism, these devices ...
