8.11. Control valve characteristics

Control valve sizing is necessary to optimize operation, provide sufficient range ability, and minimize cost. The key to correct control valve sizing is the proper determination of the required valve capacity coefficient (Cv). By definition (Cv) is the number of gallon per minute of water at 15 °C that will pass through a given flow restriction with a pressure drop of 1 lb/in2. For example, a control valve that has a maximum flow coefficient (Cv) of 12 has an effective port area in the full open position such that it passes 12 gallons per minute of water with a pressure drop of 1 lb/in2.
In using these methods, full knowledge of actual flowing conditions is essential. The primary factors that should be known ...
