Control Valve Rangeability vs Process Turndown: Verify the Real Operating Envelope
Understand why control valve inherent rangeability does not automatically guarantee process turndown. Verify minimum, normal and maximum flow, usable travel, installed characteristic and mechanical resolution.
How to Size a Control Valve: Cv, Kv, Flow Cases and Valve Travel
Learn how to size a control valve using minimum, normal and maximum flow conditions, Cv or Kv, pressure drop, predicted valve travel and severe-service checks.
