1. Classification of electric actuators:
Electric actuators generally have two types: switch type and adjustment type. Intelligent actuators can realize the selection of switch type and adjustment type. Electric actuators can be divided into linear and angular strokes according to the form of motion. They can also be divided according to the type of stop. There are two types of torque stop and stroke stop. The intelligent electric actuator at this stage can be selected according to different needs in the production process. The electric actuator has multiple transformations according to the assembled valve and deceleration mechanism (3600) And partial transformation (900)
