Judging from the position of the vent valve in the control valve assembly, under normal conditions FIC12012 should discharge material (towards the left), rather than feed it into the tower. Because the vent valve is usually located in front of the control valve. ——Actually, providing a diagram with a larger scope would help to better understand the whole process.
Precision control: The main regulator is 12011. Due to the large diameter of the pipe, the CV value set by the valve does not meet the process requirements; therefore, a valve with a smaller diameter, namely 12012, is used as a supplementary regulator
