Abstract: Valve electric actuating equipments are widely used to operate and regulate valves in modern control system, and the valve electric controller is a main section of the valve electric actuating equipment. The studying and developing of the control system has been made also. And the bus controlling system and the CDMA communicating network are brought to the scheme of the intelligent electronic actuator. Besides, in detail the author analyzed the valve the valve position locating and the compensating of flux characteristic. The whole design is adjusting and running of the instrument feasibly and reliably and the presumed function has been realized.
