The Importance Of Control Valve Selection

The regulating valve is the actuator in the automatic control system, and its application quality directly reflects the system's regulating quality. As a terminal component in process control, people have a newer understanding of its importance than in the past. In addition to the quality of the product itself and whether the user correctly installs, uses, and maintains the application of the regulating valve, correct calculation and selection are very important. Due to errors in the calculation and selection, the system starts and stops, and some even cannot be put into use. Therefore, users and system designers should understand the importance of valves in the field and pay enough attention to the selection of regulating valves.

Principles of control valve selection

1 According to the process conditions, select the appropriate structure and materials.

2 According to the characteristics of the process object, select the flow characteristics of the control valve.

3 According to the process operating parameters, select the appropriate control valve diameter size.

4 According to the requirements of the process, select the required auxiliary devices.

5 Reasonably choose the implementing agency. The response speed of the actuator should be able to meet the process
