Copper valve selection:
1. According to the choice of control function, all kinds of valves have their own functions, and they should pay attention to their corresponding functions when selecting.
2. According to operating conditions, the technical parameters of commonly used valves include the nominal pressure, the maximum allowable working pressure, the working temperature (minimum and maximum temperature), and the medium (corrosive, flammable). The above parameters should be taken into account when selecting The technical parameters of the valve are in accordance with.
3. According to the device structure selection. Pipeline system devices include pipe threads, flanges, ferrules, welds, and hoses. Therefore, the device configuration of the valve must be consistent with the device configuration of the pipeline, and the standard dimensions must be consistent.
