Cause analysis of interference source of valve electric actuator

Author: ComeFrom: Date:2022/6/24 15:02:42 Hits:331
The electric butterfly valve is composed of an electric actuator and a butterfly valve. The electric actuator rotates at 90 degrees and has two control modes: switch and regulation. The opening and closing of the butterfly valve are driven by the rotation of the electric actuator. With manual operation function, the butterfly valve can be opened and closed by manual operation in case of power failure.
There are two types of electric butterfly valves: common type and intelligent type. Ordinary type, when the motor is connected, the valve will open or close, depending on the positive and negative rotation of the motor; For intelligent type such as AC380V, after AC380V is supplied to it, the motor does not move and the internal control circuit board can work. When 4-20mA current is input to it, corresponding actions shall be taken. Close at 4mA and open at 20mA. And there is 4-20mA analog quantity feedback signal to reflect its valve opening.
