As for the determination of the output speed of the electric equipment, if there is no strict requirement for the opening and closing time of the valve, a slower speed should be selected as far as possible. Due to the unnecessary fast speed, the motor power will be increased under the same torque requirements, which will not only waste the power, improve the project cost, but also increase the volume of electric equipment, resulting in a variety of waste.
