WebSevere service control valves are used in the most difficult installations within your process plant. These installations commonly include cavitating, erosive, corrosive, noisy, high pressure, high temperature, high pressure drop, or high velocity media. WebJun 30, 2024 · The equation used to find Cv is Q = Flow in Gallons per Minute G = Specific gravity of fluid (estimated as 1 for water systems) ΔP = Differential pressure over valve (delta P) – stated in psi With this knowledge, we can quickly identify that a valve with a Cv of 10 will flow 10 GPM of water at 1 psi pressure drop across the valve without any math.
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.
