The electric actuators used in various environments differ in structure, materials, and protection methods. Therefore, the appropriate electric actuator should be selected based on the specific environmental conditions. According to engineering control requirements, the control function of an electric ball valve is accomplished by the electric actuator. The purpose of using electric ball valves is to achieve non-manual electrical or computer control of valve opening, closing, and regulation linkages. The application of electric actuators is no longer solely for saving manpower. Due to significant differences in function and quality between products from different manufacturers, selecting the electric actuator is as important as selecting the valve itself for the project. As the requirements for industrial automation continue to increase, the application of electric valves is growing, and the control requirements for electric valves are becoming increasingly stringent and complex.
Therefore, the design of electric valve electrical control is constantly being updated. With continuously increasing usage requirements and the widespread application of computers, new and diverse electrical control methods will continue to emerge. When considering the overall control of electric valves, attention should be paid to selecting the appropriate control method. For example, depending on project needs, whether to use centralized control or single-unit control, whether to link with other equipment, sequential control or computer-controlled sequential control, etc., all have different control principles. The valve electric actuator manufacturer's catalog only provides the standard electrical control principle. Therefore, the application department should conduct technical briefings with the electric actuator supplier to clarify the technical requirements.
