CV AND KV CONTROL VALVE CONVERTER
CV and KV conversion
CV to KV conversion
KV to CV conversion
The CV (also named Kv or flow coefficient) is defined as the volume of water (in gallons) at 60F which flows per minute through a valve which has a pressure drop of 1psi.
The Cv is more or less how big is the hole.
Note: The formula shown in the following drawing is a simplified calculation, the calculation of the exact Cv depends on more factors, however with this formula in many cases an approximate calculation can be made.
