Introduction
Control valves are key components in process control systems used in industrial plants.
They regulate flow automatically based on signals from control systems.
What Is a Control Valve?
A control valve is a valve that adjusts the flow of fluid in response to signals from controllers such as PLC or DCS.
It helps maintain process variables such as pressure, temperature, and flow rate.
