Control Valve Working Animation - Inst Tools
The control valve manipulates a flowing fluid, such as gas, steam, water, or chemical compounds, to compensate for the load disturbance and keep the regulated process variable as close as possible to the desired set point.
Basic Principles of Control Valves and Actuators - Overview
A “control valve” works to restrict the flow of fluid through a pipe at the command of a remotely sourced signal, such as the signal from a loop controller or logic device (such as a PLC), or even a manual (“hand”) interface controlled by a human operator.
Control valve - Wikipedia
A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. [1] This enables the direct control of flow rate and the consequential control of process quantities such as pressure, temperature, and liquid level.
What is Control Valve?- Types and How its Work - The …
How Control Valves Work? Control valves regulate the flow of a liquid or gas by opening or closing internal passages. They form part of a control loop used to control a process. The control valves respond to instructions from the controller and adjust the internal openings accordingly.
