How To Choose Electric Valve Correctly?

In pipeline engineering, the correct selection of Lined Valve is the key link to ensure the efficient and safe operation of the system. As an important part of the pipeline system, the stability and reliability of the performance of the electric valve are directly related to the operation effect of the entire pipeline system. Therefore, in the design of pipeline engineering, the correct selection of electric valves is particularly important.

The working environment of the electric valve is an important factor that must be considered when selecting. Because the electric device in the electric valve is an electromechanical device, its working condition will be significantly affected by the working environment. The following are various working environments that electric valves may face:

1. Indoor installation or outdoor use with protective measures: In this case, the electric valve is less affected by the environment, but basic requirements such as moisture and dust prevention still need to be considered.

2. Outdoor open-air installation, with erosion by wind, sand, rain, dew, sunlight, etc.: Electric valves need to have good weather resistance and corrosion resistance to cope with harsh natural environments.

3. Environment with flammable and explosive gases or dust: In this case, electric valves need to adopt special explosion-proof and fire-proof designs to ensure safety.

4. Environment in humid tropical and dry tropical regions: Electric valves need to adapt to high temperature, high humidity or dry environmental conditions to maintain stable performance.

5. Pipeline medium temperature is as high as 480℃ or above: Electric valves need to have high temperature resistance to ensure normal operation under high temperature conditions.

6. Ambient temperature below -20℃: In low temperature environment, electric valves need to have good cold resistance to prevent performance degradation or damage caused by low temperature.

7. Prone to flooding or immersion in water: Electric valves need to have waterproof performance to ensure normal operation under flooding or immersion.

8. Environment with radioactive materials (nuclear power plants and radioactive material test equipment): In this special environment, electric valves need to adopt special protective measures to ensure the safety of staff.

9. On ships or docks (with salt spray, mold, and humidity): Electric valves need to have salt spray resistance, mold resistance and moisture resistance to adapt to the marine environment.

10. Occasions with severe vibration: Electric valves need to have seismic resistance to ensure stable operation under vibration environment.

11. Occasions prone to fire: In flammable environments, electric valves must use flame-retardant materials and fire-proof designs to prevent the occurrence and spread of fire.

In short, when selecting electric valves, their working environment factors must be fully considered to ensure that the selected valves can meet the actual use requirements and ensure the safe and efficient operation of the pipeline system.
