Common faults and troubleshooting methods of valve electric actuators

2025-07-21

Electric actuator, also known as Electric Actuator, electric device, may encounter faults and troubleshooting methods when opening and closing valves in daily life, today I will summarize for you:

一. The motor of the Electric Actuator cannot start Reasons:

1. The power cord is loose;

2. Control line failure;

3. Stroke or torque mechanism failure.

Troubleshooting methods:

1. Check the power cord;

2. Eliminate line faults;

3. Eliminate stroke or torque faults.


二. The rotation direction of the output shaft of the electric actuator does not meet the regulations Reason: The power line is connected in reverse; Elimination method: Replace any two power cords;

III. Electric Actuator Motor overheating Reasons:

1. Continuous working time is too long;

2. The motor and the electric actuator are not matched;

3. Lack of phase. Elimination methods: 1. Stop running to cool the motor; 2. Check the supporting situation;

3. Check the power cord.

四. Reasons for motor shutdown during electric actuator operation:

1. Torque control action;

2. Valve failure.

Elimination method:

1. Increase the setting torque; 2. Check the valve.

五. The motor does not stop or the light does not turn on after the electric actuator is in place Reasons: 1. Failure of stroke or torque mechanism; 2. Improper adjustment of the stroke controller. Elimination method: 1. Check the stroke torque mechanism; 2. Readjust the itinerary mechanism.
