| Abstract: | In the production process control,in order to meet the particularity of certain process operations,a split-range control system is required,that is,the output of one controller is operated with two or more control valves.Based on the application of the split-range control,this paper describes the composition of the slurry catalyst tank pressure split-range control system based on the DeltaV system,the selection of the control valve switch form,the use of positive and negative effects of valve positioner,the split-range system and the control valve switch form configuration.Explain the characteristics of the DeltaV system and the configuration method of the split control system. |

| Keywords: | split-range control DeltaV system configuration control valve switch form |
