Importance of control valve selection

The control valve is an actuator in the automatic control system, and its application quality directly reflects the regulation quality of the system. As a terminal component in process control, people have a newer understanding of its importance than in the past. The quality of the control valve application depends on the quality of the product itself and whether the user installs, uses and maintains it correctly. Correct calculation and selection are also very important. Due to errors in 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 on site, and must pay enough attention to the selection of control valves.
