WebFeb 21, 2024 · When sizing a control valve, the most common approach is to calculate the flow coefficient, Cv which is a measure of the capacity of the valve body and trim. A valve Cv can be described as the number of gallons per minute (GPM) at 60 o F (15.5 o C) that will pass through a valve with an associated pressure drop of 1 psi. In simple terms, a ...
