A close-up of an industrial worker's hand in a blue uniform, operating a bright red valve on a stainless steel pipeline. The technician is carefully turning the handle to open or close the valve, regulating the flow of liquid or gas. Set in a factory or power plant, with a shallow depth of field focusing on the action, this image illustrates concepts of manual control, system maintenance, industrial processes, engineering, and energy management. |
