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
