What is Kv/Cv? How to calculate Kv/Cv?

What is Kᵥ?

Kᵥ, the flow coefficient in Metric Unit, is the flowrate in cubic meters per hour(m3/hr) that will pass through a valve with a pressure drop of (1) bar at 16ºC.

Where is Kᵥ used?

Cᵥ is used to determine the valve size that will best allow the valve to pass the required flow rate while providing stable control of the process fluid.

What is Cᵥ?

Cᵥ, the flow coefficient in Imperial Unit, is the number of U.S. gallons per minute that will

pass through a valve with a pressure drop of (1) psi at 60°F.
