Basis for Fluid Control Valve selection

In addition to the pipeline parameters, the Fluid Control Valve should pay special attention to the environmental conditions of its obligations. Since the electric device in the Fluid Control Valve is an electromechanical device, its obligation status is greatly affected by its obligation environment.

Under normal circumstances, the Fluid Control Valve has the following obligations:

1. Indoor equipment 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 pipeline medium temperature is up to 480 ° C or more;

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

7, vulnerable 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, occasions with severe vibration; occasions prone to fire;

For the Fluid Control Valve in the above environment, the structure, materials and protection methods of the electric device are different. Therefore, the corresponding valve electric device should be selected according to the above-mentioned obligation environment.
