FLOW CHARACTERISTICS
The approximate flow rate through a valve can be calculated as follows:
where; Q = flow rate in gallons (U.S. Std.) per minute
Cv = valve constant
P = pressure drop across the valve in pounds per square inch
G = specific gravity of the media of relative to water
Note: The values derived from the flow equation are for estimating purposes only. Product variances
or systemic factors may alter actual performance.
