Flow Coefficients Cv Values - SCV Valve, LLC
WebFor the valve characteristics in Above Figure, for example, CV = 40. The way q varies when the pressure is kept constant (normally the rated pressure drop across the valve for maximum flow) and the way C changes as the valve opening x changes, may be available for a particular valve, provided by the manufacturer in tabulated format. WebFlow 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.
