What are Control Valves? | Selection and Types of Control ...

The control valve is an automated valve that can make precise adjustments to regulate and monitor any commodity flowing through a piping system. The function of a control valve is to provide throttling control in response to signals from a control system, using an actuator and a positioner. They are considered the ''final control element'' in an automated and usually very …
