The main methods to solve the leakage of motorized valves are:

1. First of all, the reliability of the sealing structure must be improved in design.

2. The selection of sealing materials must be based on different operating conditions and reasonable selection of different sealing structures and sealing materials.

3. There must be accurate and detailed standard requirements for the processing, size and other aspects of sealing structures and seals.

4. Check whether the electric device and valve body are installed incorrectly or have deviations in the installation, which may accelerate valve leakage.

5. Regularly maintain, inspect and calibrate the electric actuator and valve body.

6. Process improvement, using more advanced processes to reduce the probability of valve leakage.
