Description of a valve actuator for electric actuators

When the electric actuator is driven by a valve, the demand in the market increases, and the types and types of electric actuators are many. The electric actuator can be divided into: according to the action mode: 1, angular stroke: 0~90° angular stroke; 2, multi-rotation: need to run more than 360 ° to achieve the opening and closing of the valve; 3, straight stroke: the output is the force, the resulting linear displacement. Electric actuators are used in the system. The angular stroke is widely used in ball valves and butterfly valves due to the use of 0 to 90 degrees. The multi-turn type is mainly used in the gate valve shut-off valve, and the multi-turn type is mostly used in the regulating valve. gate. Therefore, customers should rely on the advantages of electric actuators to select the right one when choosing the right valve. Choosing the right actuator can greatly improve the working efficiency and also enable the valve to operate normally and guarantee the service life? It can be seen the importance of it.
     
    Electric actuators are suitable for a variety of applications in various industries such as power, metallurgy, petroleum, chemical and light industry. After the electric actuator is processed by computer operation, the terminal drives the corresponding linear displacement of the AC motor output; a high-performance conductive plastic potentiometer is used as the position sensor, which has high ** degree and long life; the control component has built-in memory chip, when electric execution The input voltage is lower than the rated voltage, and the field data is automatically recorded. When the input voltage returns to normal, the system can continue to work normally; the single-phase AC 220V power source is used as the source power; the AC synchronous motor is used as the drive motor. It will not be damaged in short-time overload operation; it is equipped with a standard RS-485 communication port. It has various motion change functions required by the regulating valve itself.
