28+ Valve Cv Calculator. It allows you to calculate the flow or cv (flow coefficient) to make the relationship visible between the pressure drop (the difference in pressure between two. Chose the sheet that corresponds to the service the valve will be submitted to (liquid, gas,.

Valve flow coefficient (cv) cv is the flow (in gpm) of water through the valve with a 1psi pressure drop. The cv flow calculator helps determine the flow coefficient (cv) of a valve, which represents the valve’s capacity to allow fluid flow at a given pressure drop. This cv flow calculator will help you understand how the capacity of a valve to let fluid flow through is measured.
