Ball valve installation and use

1. Indoor devices or outdoor applications with protection methods;

2. Outdoor open-air installations, with wind, sand, rain, sun and other erosion;

3. It has a flammable, explosive gas or dust environment;

4. Wet tropical and dry tropical environment;

5. The temperature of the pipeline medium is above 450 °C;

6. The ambient temperature is below -20 °C;

7. susceptible to flooding or immersion in water;

8. Environment with radioactive materials (nuclear power stations and radioactive material testing devices);

9. The environment on the ship or dock dock (with salt spray, mold, moisture);

10. Where there is severe vibration; occasions where fire is prone to occur;

For the electric ball valve in the above environment, the structure, material and protection of the electric device are different. Therefore, the corresponding valve electric device should be selected according to the above-mentioned obligation environment. According to the engineering control requirements, for the electric ball valve, its control function is completed by the electric device. The purpose of applying the electric ball valve is to perform non-manual electrical control or computer control on the opening, closing and adjustment of the valve. Electric device applications are not just for diligence. Since the functions and quality of products from different manufacturers are quite different, it is equally important to select the electric device and the valve to be selected. As the requirements of the industrial automation level have always been improved, on the one hand, the application of electric valves is increasing, and on the other hand, the control requirements for electric valves are becoming higher and higher, and more and more complicated. Therefore, the design of electric valves in electrical control is also constantly updated. With the increasing use requirements and the widespread use of computers, new and diverse electrical control methods will always emerge. For the overall control of electric valves, attention should be paid to the choice of electric valve control. For example, depending on the needs of the project, whether the centralized control mode is applied, whether it is a single control mode, whether it is linked with other devices, the order control is still applied to the computer sequence control, etc., and the control principles are different. The valve electric device manufacturer sample only gives the standard electrical control principle, so the application department should make technical disclosure with the electric device consumption factory and clearly understand the technical requirements.
