Plug Valve Cv

Plug Valve Cv. 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 cv tells you how to properly size your valve so it has minimal effect on the hydraulic efficiency you’ve engineered into your system.

An arrow stamped on the valve body indicates the flow direction. What is flow coefficient (cv)? Flow coefficients cv values the flow coefficiency (cv) of a valve is the rate of gallons per minute of water at 60° f through a fully opened valve at a pressure drop of 1 psi across the valve.
