Control valves are essential components for regulating the pressure, temperature and flow rate of various systems. They work by adjusting the pressure or flow on either side of a valve, using an actuator or other method. By making these adjustments, it is possible to fine-tune a system so that it operates more reliably and with greater precision. In this article, we will look at the principles of control valves and how they operate, as well as some tips for maintaining them. We’ll cover topics such as types of control valves, sizing, and the importance of pressure drops when controlling fluid.
