Flow control valves (FV)

Flow control valve (FV)
A flow control valve or FV is a type of valve that helps regulate and control the flow rate of a fluid in a system. It works by changing the size of the valve opening to maintain a consistent flow rate within a specific range, no matter what’s happening upstream or downstream
If the flow rate goes too high, the valve reduces the size of the opening to limit the flow. If the flow rate goes too low, the valve increases the size of the opening to allow more fluid to flow.

Flow control valves are used in many industries, like water treatment, chemical processing, and oil and gas. They help control the flow of liquids and gases in pipelines and tanks. Flow control valves come in different types, including globe valves, needle valves, and ball valves, and can be controlled manually or automatically.

A flow control valve gets a control signal from a flow meter (as in the image above) to adjust the valve element position, maintaining the desired flow rate. In manual flow control valves, the operator adjusts the valve element position to control the flow rate.
