In the paper, i use the success of valve actuators controller from home and abroad as an reference.On this basis ,followed by the rules ofsafe 、reliable、simple、advanced.Firstly, upon request made to the system,i came up with the idea of transmission system design, followed by access to information used to determine the motor type, and then calculatethe main parameters are analysis to determine the appropriate transmission components selected. Then rough design of its structure, then according to the design criteria for the size and design theory calculation and verification. The last part of the design is about electric control. As the valve is widely used, manual mechanical adjustment of the way in many cases no longer apply, the design can work under safer conditions, and efficiency many times, so the design of electric valve controller has practical significance. Motor controllers for industrial process control system a very important field drive, a compactand easy to wire, high precision, simple operation, the advantages of intelligence, isan economical and practical products, and has broad market prospects of development.
