Advances in Valve Technologies and Drive Systems for Efficient Gas–Liquid Flow Regulation

Abstract

In current chemical and bioengineering production processes, the transportation of gases and liquids is a critical component of the entire process. During the transmission process, the valve system used to regulate and control the flow rate and conductivity of gas-liquid mixtures serves as a vital control component. However, existing research has primarily focused on individual aspects of valves and their drive mechanisms, lacking a comprehensive comparison from both mechanical and automation perspectives. This gap has led to issues such as improper selection and poor performance in practical applications. To address this issue, this paper conducts a comprehensive analysis of mainstream valves and their integration with pneumatic, electric, and electro-hydraulic drive systems. Additionally, this paper focuses on the latest valve control methods, identifies their innovative aspects, and analyzes their advantages and disadvantages, providing new insights for industrial production with higher efficiency, offering practical guidance for making optimal choices in various industrial scenarios. This work not only aids in making more informed engineering decisions but also points the way toward the future development of smart fluids.
