What Is Control Valves ? |
|
Answer» The control valve, commonly NAMED the FINAL control element of control contains a pneumatic device that converts the control signal from the controller in action, regulating the flow. 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. This enables the direct control of flow rate and the CONSEQUENTIAL control of process quantities such as pressure, TEMPERATURE, and liquid level.
