At present, green and low carbon has become the consensus of the mainstream society in the world. The Chinese government has committed to strive to achieve carbon peaking by 2030 and carbon neutrality by 2060. To this end, while vigorously developing non-fossil energy, "removing coal and reducing oil" and gradually reducing the share and quantity of natural gas in energy consumption have become the main theme of the future development of the energy sector. In the context of "dual carbon", the concept of "green finance" is heating up. Some people propose to significantly reduce investment in fossil energy and require financial institutions to stop providing loans for it. The argument that oil and gas is a "sunset industry" has resurfaced. But the completion of the energy tran

In many control applications, the valve positioner is one of the important accessories of the regulating valve. Especially for a specific application, if you want to select an applicable (or excellent) valve positioner, you should pay attention to the following factors: 1. Can the valve positioner achieve "split_ranging"? Is it easy and convenient to realize "split process"? The "split range" function means that the valve positioner only responds to a certain range of input signal (such as 4 ~ 12mA or 0.02 ~ 0.06mpag). Therefore, if you can "split range", you can control two or more regulating valves successively with only one input signal contact according to the actual needs. 2. Is the adjustment of zero point and range easy and convenient? Can the zero point and range be
