Control Valve

Control valves regulate flow, pressure, or temperature by modulating the valve opening in response to a control signal, making them central to process automation. This tag gathers articles on control valve design and operation, including globe-style and rotary control valves, actuator and positioner selection, flow characteristic curves, and sizing fundamentals. Content also covers installation best practices, common problems such as hunting, cavitation, and leakage, and how control valves compare with manual isolation valves. Written for process and instrumentation engineers who need practical, field-tested guidance.
