At the same time, electric valve actuators at this stage, led by some foreign brands, have introduced many of the latest control technologies. For example, non-invasive design, unpack free commissioning, replacing mechanical travel controller with absolute coding travel controller, push-pull torque sensor, wireless remote control and field bus, etc. The actuator has entered the stage of intelligent and non-invasive application. However, to a certain extent, these control technologies have put forward higher requirements for the number of I/O of MCU, the type of integrated peripherals, and the running speed. The original traditional MCU cannot meet the requirements, while MCU with SOC concept obviously meets the new design requirements.

At present, the electric control valve is most suitable for the environment with high sealing requirements, high life requirements, and the operating temperature must be controlled at - 10 ℃~150 ℃. Take the soft sealing eccentric butterfly valve as an example, which is more suitable for the two-way opening and closing of ventilation and dust removal pipelines. It can be seen in the fields of power, petrochemical, metallurgy, etc.
