Application of electric actuators in valve control

The application of electric actuators in valve control is mainly reflected in their ability to control the opening and adjustment of valves through electric means, and they are widely used in various industrial fields. Electric actuators, also known as valve electric devices or electric heads, are mainly divided into two categories: angular stroke and linear stroke. The former controls the valve by rotating, while the latter controls the valve by linear motion.
Basic working principle of electric actuator
The working principle of an electric actuator is to drive the gear set in the gearbox through a motor to achieve the function of opening or adjusting the valve. Angular stroke actuators control valves through rotational motion and are suitable for situations that require rotational operation; The linear actuator controls the valve through linear motion and is suitable for situations that require linear control. Electric actuators usually use AC AC or DC DC as the driving energy source, and can choose electric switch type or electric regulation type according to demand.
Types and characteristics of electric actuators
Angular stroke actuator: suitable for situations that require rotation angle control, such as the rotation operation of robotic arms, control of cutting equipment, etc. Its rotation speed is slow and suitable for fine adjustment.
Straight stroke actuator: suitable for situations that require linear movement, such as welding, spraying, and other processes in automotive manufacturing. Its movement speed is fast, suitable for rapid response and control.
Practical application cases
In the industrial pipeline valve industry, electric actuators are often combined with ball valves, butterfly valves, gate valves, etc. to form electric valves and electric control valves. For example, on automated production lines, linear actuators are used for grasping, assembling, and handling robotic arms, while angular actuators are used for rotating robotic arms and controlling cutting equipment. In addition, electric control valves are widely used in industries such as chemical, petroleum, and metallurgy to precisely control the flow rate and pressure of fluid media.
