What does the execution structure on PID mean? Or is there any material where I can find out about it?

Things like “single/double-acting cylinder actuation structure,” “electric actuation structure,” “pneumatic diaphragm actuation structure,” and so on – there are about a dozen such types. I’ve searched for a long time but haven’t found much information on them; I haven’t seen any related details for ordinary pipes either... I’d appreciate some advice~~ PS: I’m new to piping systems, and trying to figure out the symbols on various pipes in order to understand PID values; I still can’t make sense of even one pipe after spending an entire afternoon on it. . I feel dizzy and my head is heavy. . . :Q :Q
It should be the actuator of the instrument; if that’s the case, you can look for some samples of instrument valves to take a look at.
Reply to 2# zero229: Thank you so much~~~ It’s exactly this thing~ “The actuator uses liquids, gases, electricity, or other forms of energy, and converts them into driving force through motors, cylinders, or other devices.” The basic actuator is used to drive the valve to the fully open or fully closed position. The actuator of the control valve enables the valve to be moved to any position with precision. Although most actuators are used for opening and closing valves, today’s actuators go far beyond simple on/off functions; they include position sensing devices, torque sensing devices, electrode protection devices, logic control devices, digital communication modules, and PID control modules, all of which are housed within a compact enclosure. ”
