The electric control valve is composed of electric actuator and control valve. Its main features are as follows:

1. Light weight, beautiful appearance.

2. In terms of function, it can replace many products with incomplete functions, simplify the modeling, and solve the problems of complex factory management, complex model selection and heavy maintenance workload.

3. The adjustable ratio of the electric control valve is large, generally up to 100, and good adjustability can be guaranteed from 10% to 90% of the opening.

4. It has stable operation and high reliability, and can solve the fatal structural defect of traditional valve with large leakage.

5. With excellent on-off characteristics and zero leakage, it solves the fatal structural defect of traditional valve with large leakage.

6. Good ability to overcome pressure difference, anti blocking function, the simplest flow path, no resistance regulation, the largest Kv value, and the best "self-cleaning" performance.

7. The flow characteristic of the electric control valve is approximately equal percentage. However, due to the pressure difference between the front and the back of the valve, the actual curve of the traditional control valve will have a large distortion, but it is also relatively small, so it has not only good regulation performance, but also good economy and energy saving.

8. Compared with the pneumatic control valve, the power supply for the electric control valve is convenient and economical, which saves a series of troubles in establishing the gas source station.

9. The electric regulating mechanism has high precision, resolution up to 1 / 1000, low operation cost and no need of maintenance.

10. According to the actual use environment, PTFE lined ceramic ball valve or full lined ceramic hard seal ball valve can be used to obtain higher corrosion resistance and wear resistance.
