By receiving the control signals output by the control unit, process parameters such as medium flow rate, pressure, temperature, and liquid level can be adjusted; in other words, the control valve serves as the final barrier in the process loop! Therefore, how to properly select control valves to achieve the best control effect becomes a crucial issue. ①\"Selection principles\" for the inherent flow characteristics of control valves: The selection of control valves should be based on a comprehensive consideration of the characteristics of the control system, the sources of disturbance, and the S value (valve resistance ratio). ②Selection of control valve material ③ Selection of control valve leakage rate and flow rate ④ Selection of control valve accessories ⑤ Installation of the control valve」
