The definition of cv is the number of gpm (gallons per minute ) that will pass through the control valve with a pressure drop of 1psi. Cv = (25 gpm) (1 /.

Cv by definition is the number of gallons per minute (gpm) a valve will flow with a 1 psi pressure drop across the valve. It applies to the factor of the head drop (δh) or pressure drop (δp) over a valve with the flow rate q.

Cv=gpm/ ( (sq rt (p)). The valve flow coefficient cv or its metric equivalent kv has been adopted universally as a comparative value for measuring the capacity of control valves.

Flow rate is expressed as cv or kv, depending on the system of measurement being used (imperial or metric, respectively). The coefficient of flow or c v value is the number of us gallons of water the valve will pass with a differential pressure of 1psi through the valve at 60°f.

The minimum required cv value is often listed in a valve’s product description, or wherever its specifications are found. C v varies with both style and size of valve, but provides an index for comparing liquid capacities of different valves.

K v is the metric value of c v and is calculated as k v =c v x 0.85. It is technically defined as “the volume of water at 60°f (in us gallons) that will flow through a valve per minute with a pressure drop of 1 psi across the valve.”

For example a valve with a cv. Cv value = flow coefficient in imperial units.

### The Definition Of Cv Is The Number Of Gpm (Gallons Per Minute ) That Will Pass Through The Control Valve With A Pressure Drop Of 1Psi.

It is actually possible to convert kv and cv and have the expression in the right unit for the calculation of interest. It applies to the factor of the head drop (δh) or pressure drop (δp) over a valve with the flow rate q. For example a valve with a cv of 10 will flow 10 gpm with a 1 psi pressure drop.

### The Valve Flow Coefficient According To The Jis Standard, Represents The Flow Capacity In Us Gallons/Minute Of 60° F Pure Water When It Is Flowing Through The Valve With A Pressure Difference Of 1 Psi At The Specified Travel (Operation Range).

For example a valve with a cv. Cv is the number of us gallons that goes through the valve at 60f and with a pressure drop of 1 psi. The coefficient of flow or c v value is the number of us gallons of water the valve will pass with a differential pressure of 1psi through the valve at 60°f.

### The Valve Flow Coefficient Cv Or Its Metric Equivalent Kv Has Been Adopted Universally As A Comparative Value For Measuring The Capacity Of Control Valves.

### Same Model Valve Has Different Coefficient For Each Diameter.

The cv tells you how to properly size your valve so it has minimal effect on the hydraulic efficiency you’ve engineered into your system. The flow coefficient for a control valve which in full open position passes 25 gallons per minute of water with a one pound per square inch pressure drop can be calculated as: The flow coefficient, cv, is a dimensionless value that relates to a valve’s flow capacity.

### Kv Is The Flow Coefficient In Metric Units.

Cv by definition is the number of gallons per minute (gpm) a valve will flow with a 1 psi pressure drop across the valve. Gallons per minute of water at 60°f that will flow through a control valve at a specified opening when a pressure differential of 1psi is applied across the valve: It is defined as the flow rate in cubic meters per hour [m3/h] of water at a temperature of 16º celsius with a pressure drop across the valve of 1 bar.
