When Valve Installed characteristic matches Inherent characteristics?

Control Valves
1

The installed characteristic of a control valve matches the inherent characteristic of a control
valve:

  • When the friction losses in the pipeline are negligible and the major drop is due to control valve.

  • When the valve authority approaches 1.

  • When the valve pressure drop at the maximum flow rate is nearly 1/3rd of the overall system pressure drop (valve + line).
