The valve flow coefficient (C v) is a convenient way to represent flow capacity of a valve across a range of fluids and process parameters. The C v calculator will calculate either C v or flow using the supplied additional parameters of fluid, inlet and outlet pressure, and fluid temperature.

기술사사무소차  Note: When Cv required is between two valve sizes and closer to smaller valve size, re-size for Cv using critical pressure (1/2 absolute) as pressure drop. If this  Butterfly valve Cv values vary with the disc angle and valve size. In the chart below, we show the approximate Cv value of butterfly valves ranging from 2" to 24"  passes through a valve at a pressure drop of 1 PSI. Flow for a given Cv is typically calculated from the following formula. Where: Q = Valve flow rate in gallons  FLOW FORMULATION USING Cv COEFFICIENT. FLOW COEFFICIENT “Cv” DEFINITION: flow rate (gallons/minute) of water (60° F) with 1.0 psi pressure drop   Lowflow Mark 708 Fractional Flow Control Valve for Ultra-Low Cv · For steam, air, gas, oil, water, and chemical service · Cv ranges from 0.00001 to 4.0 available in   Some manufacturers provide tables showing the percentage travel and the valve coefficient Cv at each 10%, or each 10 degrees for rotary valves. 1 Jan 2001 control point and operate with the valve plug too close to the seat, resulting in undue wear of the plug and seat.

Table 2 was prepared for conversion from water, which has a viscosity of 1.12 centistokes at 60°F, to fluids of higher viscosity. Control valve CV refers to the flow coefficient of the valve. It applies to the factor of the head drop (Δh) or pressure drop (ΔP) over a valve with the flow rate Q. Calculating control valve CV. When Sizing (calculating which size valve is needed for your application ) a control valve specialist needs to calculate the flow coefficient. Control valve CV refers to the flow coefficient of the valve.

It is technically defined as “the volume of water at 60°F (in US gallons) that will flow through a valve per minute with a pressure drop of 1 psi across the valve.”. 2018-02-21 The ValveMan explains what a CV, or flow coefficient, is and how to calculate it. For more information about valves visit https://ValveMan.com 2018-12-26 The definition of Cv is the number of GPM (Gallons per minute) that will pass through the control valve with a pressure drop of 1psi.
