Working environment and medium: When selecting a flange ball valve model, it is necessary to understand what working environment and medium the valve will be used for, such as the temperature, pressure, acidity, corrosiveness, and other characteristics of the medium. Select corresponding valve models for different working environments and media requirements, such as high-temperature, corrosive, wear-resistant, etc.
1. Working environment and medium: When selecting a flange ball valve model, it is necessary to understand what working environment and medium the valve will be used for, such as the temperature, pressure, acidity, corrosiveness, and other characteristics of the medium. Select corresponding valve models for different working environments and media requirements, such as high-temperature, corrosive, wear-resistant, etc.
2. Required valve functions: Flange ball valves are usually used to control the flow and pressure of the medium, and different working scenarios have different requirements for valve control. For example, if precise flow regulation is required, an adjustable flange ball valve model should be selected; If quick switching is required, the cut-off type flange ball valve model needs to be selected.
3. Valve size and connection method: When selecting a flange ball valve model, the connection method and size of the valve should be determined based on factors such as pipeline size, pipeline material, installation position, etc., such as nominal pressure rating, flange standard, etc., to ensure consistency in valve connection and use.
4. Rated parameters used: When selecting a model, it is necessary to understand the nominal diameter, nominal pressure, nominal diameter of the gate, nominal pressure, operating pressure, and temperature of the valve and pipeline connection. Users should strictly consider and inspect the design indicators when selecting, in order to avoid faults or accidents caused by valve deviations due to improper use.
5. Identify the special requirements of the selected model based on the control unit of the valve.
When selecting a flange ball valve model, it is necessary to comprehensively consider the actual application requirements, including the valve's usage environment, medium characteristics, valve function, unified matching between structure and parameters, etc., to ensure the correctness and practicality of the selection.
