The intelligent electric actuator adopts variable frequency deceleration. The operating speed of the electric actuator changes according to the position value. When the given value is larger than the current position value, the electric actuator runs at a faster speed to the vicinity of the given value, and then reaches the given point at a slower speed, so that 1. the adjustment accuracy value is high 2. the impact on the system valve is avoided, Elimination of water hammer effect · Intelligent electric actuator can display the operation of the electric actuator in real time, the current torque and the current position in real time · Intelligent electric actuator can diagnose faults by itself and give corresponding alarm signals · Intelligent electric actuator shall be of non intrusive design and generally set with infrared ray, It can also be set with the infrared port or data line of the personal computer. The intelligent electric actuator adopts a variety of control methods including bus technology. (It is used for closed-loop automatic control, and can receive and output 4-20mA standard control signals to achieve DCS control
