1、 Performance characteristics of electric control valve:
The electric control valve is composed of an electric actuator and a control valve. Its main characteristics are: 1. Light weight and beautiful appearance. 2. Functionally, it can replace many products with incomplete functions, simplify the modeling, and solve the shortcomings of complex factory management, complex model selection, and heavy maintenance workload. 3. The adjustable ratio of electric control valve is large, generally up to 100, and good adjustability can be guaranteed from 10% to 90% of the opening.
4. Stable operation and high reliability 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 valves with large leakage.
6. Good ability to overcome differential pressure, anti blocking function, the simplest flow path, unimpeded 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 before and after the valve, the actual curve of the traditional control valve will be greatly distorted but also relatively small, so it not only has good regulation performance, but also has good economy and energy conservation.
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 operating cost and no need for maintenance.
10. According to the actual use environment, the PTFE ceramic lined ball valve or the full lining ceramic hard seal ball valve can be used to obtain higher corrosion resistance and wear resistance.

Disassembling the electric ball valve is a common way to check problems, and it is also a way that many people will do when maintaining the ball valve regularly. When disassembling the ball valve, everyone should pay attention to that individual parts need to be placed very carefully, preferably on a soft and smooth cloth surface.
