28+ Calculate Cv For Valve. The valve flow coefficient (cv) is defined as. Valve flow coefficient (cv) cv is the flow (in gpm) of water through the valve with a 1psi pressure drop.

The standard formula for calculating flow cv is q = cv√δp/g, where q represents the flow rate in gallons per minute (gpm), cv is the flow coefficient, δp is the pressure drop across the valve. Valve flow coefficient, referred to as cv, is a measure of a valve’s capacity to pass fluid. The valve flow coefficient (cv) is defined as.
