Electric butterfly valve operating environment

Electric butterfly valve is a kind of automatic valve, generally used in the manual can not be operated in the working environment, specifically, there are the following:

1. The medium in the pipeline is inflammable and explosive gas or dust;

2. There is salt mist, mould and damp environment on the ship or dock;

3. Occasions when the pipeline will vibrate violently;

4. Dangerous occasions prone to fire;

5. Environment in humid tropics and dry tropics;

6. The medium temperature of the pipeline is as high as 480℃ and above;

7. Indoor or outdoor pipes requiring protective measures;

8. Outdoor environment frequently eroded by wind, sand, rain and dew, sunshine, etc.;

9. The ambient temperature of the installation site is below -20℃;

10. Environment prone to flooding or long-term flooding;

11. Toxic gases, radioactive substances and other environment harmful to human health.

Electric butterfly valve switch action speed can be adjusted, simple structure, easy to maintain, can be used to control the flow of air, water, steam, all kinds of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid.Electric butterfly valve device is an indispensable device to realize program-control, automatic control and remote control of the valve. Its motion process can be controlled by the size of stroke, torque or axial thrust.

Since the operating characteristics and utilization of the electric butterfly valve depend on the type of valve, the working specification of the device and the position of the valve in the pipeline or equipment, the correct selection of the electric butterfly valve device is crucial to prevent overload (working torque is higher than the control torque).
