The electric actuator refers to an electrical signal such as an electrical signal such as an energy source in the control system. The amount of manipulation is changed according to the size of the signal, so that the amount of material or energy of the input or output control object changes, reachabable Adjustable.
In industrial production, the electric regulatory valve is widely used. The electric regulating valve is composed of two portions of the actuator and the adjustment mechanism (valve). The valve portion has been described above, and therefore, only the electric actuator is introduced in the electric regulator.
Advantages and disadvantages of electric actuators
Advantages: Energy-friendly energy, sensitivity, fast signal transmission speed, is suitable for use with electronic computers.
Disadvantages: Electric actuators are generally not applicable to fire prevention and explosion-proof, and the structure is complex and expensive.
