Before starting the electric ball valve, first check whether all the states before electric control are correct.

1. First confirm whether the manual device has returned to the electric position.

2. Whether the fluid state in the pipeline is consistent with the next step of electric control mode.

3. If there is remote or local control function, you need to switch the remote or local control mode correctly.

4. After all conditions are correct, start the electric control mode.

5. When operating the valve on site, the opening and closing instructions of the valve and the movement of the valve stem should be monitored, and the degree of opening and closing of the valve should meet the requirements.

6. During the opening and closing process of the valve, if the signal indicator light is wrong and the valve makes abnormal noise, it should be stopped in time for inspection. After successful operation, the power supply to the electric ball valve should be turned off.

7. When operating multiple valves at the same time, pay attention to the operating sequence and meet the production process requirements.

The safety precautions for electric ball valves are as follows:

1. Before operation, it is necessary to check the working status and connection condition of the electric ball valve to ensure that there are no abnormalities.

2. Operators need to understand the instruction manual and safety standards of electric ball valves and operate them in accordance with relevant regulations.

3. Operators need to wear personal protective equipment that meets safety standards, such as safety shoes, gloves and glasses.

Before opening or closing the electric ball valve, the operating procedures need to be strictly followed to avoid danger caused by misoperation.

4. Operators need to set obvious warning signs on the electric ball valve to remind others to pay attention to safety.

5. During operation, excessive force or distortion of the electric ball valve should be avoided to avoid damaging the equipment.

6. When an abnormality occurs with the electric ball valve, it should be stopped immediately and the relevant departments should be notified for inspection and maintenance.

7. Regularly inspect and maintain the electric ball valve, clean and lubricate its action parts to ensure its normal operation.

8. Electric ball valves that have not been used for a long time should be stored in a dry and ventilated place, and protective measures should be taken to avoid corrosion and damage.

9. Operators need to receive regular safety training, understand the use of new technologies and new equipment, and remain vigilant about 10. electric ball valves and their surrounding environment.
