They use electricity as a power source, receive analog or digital standard signals sent by control equipment, and change and operate valves by converting these signals into corresponding mechanical displacements such as angles or strokes, so that the adjustment parameters (pressure, flow, temperature, liquid level, etc.) can be automatically adjusted. Electric actuators can enable the production process to proceed according to predetermined requirements. It is an extremely important execution device in process automatic control systems and is widely used in electric power, petroleum, chemical, metallurgy and other industries.
