What is A Control Valve ?
- 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.
Types Of Control Valves
- Pneumatically actuated control valve: a pneumatic pilot or liquid level controller
- Electrically actuated control valve: an electric pilot, electric liquid level controller, Programmable Logic Controller (PLC), or Remote Terminal Unit (RTU)
