Level control valves (LV)

Level control valves (LV)

Level control valve or LV is a device used to maintain a consistent fluid level within a tank or vessel. It works by regulating the flow of liquid into or out of the tank, in response to changes in the fluid level. The valve ensures that the fluid level remains within a specific range, which can help prevent overflows, underflows, or other issues.

The level control valve is typically installed in a pipeline or vessel that is connected to the tank or vessel. It is connected to a level sensor that monitors the fluid level within the tank. When the fluid level rises above or falls below the desired set point, the level control valve adjusts the flow of liquid accordingly.

For example, if the fluid level rises above the desired set point, the valve will reduce the liquid flow into the tank, which will lower the level. Conversely, if the fluid level falls below the desired set point, the valve will increase the flow of liquid into the tank, which will raise the level.

As depicted in the image, the Level control valve or LV is connected to a level transmitter that communicates with the valve to operate and control flow accordingly.
