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.

Q = Cv
