Control valve flow coefficients

Cv-values presented in these control valve sizing coefficient tables are based on laboratory measurementsusing room temperature water according to the following phases:

1 Valve is mounted in a straight pipeline and pressure drop Δptotal is measured at the flow rate q, as shownin figure 1.

2 Valve is taken off the pipeline, and the upstream and downstream pipes are joined together, and pres-sure drop Δppipe is measured at the same flow rate q used in previous measurement.

Pressure drop caused by a valve alone Δpvalve is then:

Cv-value of the valve is:

where N1 = 0.865 for units [m3/h], [bar]= 1.0 for units [gpm], [psi]

While valve nominal size is smaller than attached piping, the effect of the reducer(s) to the valve capacity istaken account using Fp factor and then replacing Cv with Fp * Cv, which is calculated by Nelprof using stan-dard sizing equations. In a case where pipe diameter D is the same size on both side of the valve, the fol-lowing graph (figure 2) can be used for a quick evaluation.

Nomenclature used in the control valve sizing coefficient tables

Marking used to identify reduced Cv-trims

The reduced Cv-trims can be identified from the '/' sign after the valve nominal size in the SIZE column in theCv-tables. The number after the '/' sign represents the reduction number of the Cv-trim. For example, in theCv-table for R-series V-port segment valves, the marking 25/1 (1/1) in the size column represents the firstreduced Cv-trim for the R-series size DN 25 (1") V-port segment valve. Correspondingly, the marking 25/4 (1/4) represents the fourth reduction.

In Nelprof, enter the '/' sign and reduction number after valve nominal size for the valve size. For example, forfirst reduction for a DN 25 (1") valve size, enter 25/1 or 1"/1 for valve size.

Other nomenclature

Cv = Valve flow coefficient, which represents valve capacity

h = Relative opening, which is calculated for rotary type of valves as follows:h =100% * (actual opening in degrees - h0) / (maximum opening in degrees - h0)where the h0 represents the initial opening in degrees. Some rotary valves have to be openedby the amount of initial opening h0 before the fluid begins to flow through the valve. The initialopening values for different valve styles are listed at the end of this book.

Cv/d2 = Cv divided by the square of the valve inlet diameter d in inches

The factors FL, xT, and z are presented as a function of Cv/d2 in order to count for different

geometries in different size control valves. The Cv/d2 values correspond to average Cv/d2

relation of the valve at 10 % opening intervals, and can be used for rough manual calculationsas such. The Nelprof program interpolates sizing factors based on accurate Cv/d

2 values

FL = Pressure recovery factor according to standards IEC 60534 and ISA S75

xT = Pressure drop ratio factor according to standards IEC 60534 and ISA S75

z = Valve specific characteristic pressure drop ratio used in hydrodynamic noise predictionaccording to standard VDMA 24442

ΔLf = Hydrodynamic noise coefficient, which is a valve type related factor in control valve hydrody-namic noise prediction

xf = Pressure drop ratio, which is calculated as follows:xf = (p1-p2)/(p1-pv), in which pv represents vapor pressure.Hydrodynamic noise coefficient ΔLf affects liquid fluid control valve noise level only if pres-sure drop ratio xf is greater than z

XR = Scaled pressure drop ratio for cavitating flow, which is calculated as follows:XR=(xf-z)/(1-z)

ΔLg = Aerodynamic noise coefficient, which is a valve type related factor in control valve aerody-namic noise prediction

x = Pressure drop ratio, which is calculated as follows: x=(p1-p2)/p1

METAL SEATED V-PORT SEGMENT VALVE (Nelprof® code RB, RE)

This new generation control valve is based on R21-series and carries the appreciated qualities of thisdesign. Improvements are made in trim and stem pack-ing to reduce friction and eliminate mechanical clear-ances. The design has both Pulp&Paper industry (RB)and Energy&Hydrocarbon industry (RE) versions. RB/RE is a valve, which can truly help to improve processperformance and reduce variability. Energy&Hydrocar-bon industry valves are fire-tested. Available with smallCv trims. Available in flanged bodies to fit ANSI 150 and300; DIN 10, 16, 25 and 40; and JIS 10, 16 and 20 pipeflanges.

METAL SEATED V-PORT SEGMENT VALVE FOR MEDIUM CONSISTENCY PULP (Nelprof® code R2_S)

The R-series V-port segment control valves have char-acterized flow opening to provide optimum inherentequal percentage flow characteristics. Continuous seg-ment/seat contact and concentric rotation provide easyhandling of fibrous fluids and very high flow rates. Theflow path of the valve is continuously enlarged towardsvalve outlet to assure free flow of thick slurries or fibrousfluids.

Series 835 Wafer-Sphere® high performance butterflyvalves provide excellent control performance and bi-directional bubble tight shut-off to 100 psi (7 bar). Theflexible seat design provides low pressure sealing andlong seat life. The double offset disc ensures extendedcycle life and low maintenance costs. An optional lowtorque seat allows smaller actuators to be selected.Fire-Tite® valve construction is also available. Waferand single flange lugged bodies mount betweenANSI 150 and DIN PN 10, 16 and 25 flanges.

MAPAG BK, ECCENTRIC METAL SEATED BUTTERFLY VALVE,RATING ANSI 150 (Nelprof® code BK wafer-150)

The Type BK stands for cryo. The values for the stan-dard valve are based on single U-shape seat construc-tion and for standard material strengths. The material aswell as the seat selection might have an effect on valvedimensions and Nelprof sizing due to strength calcula-tions. The valve is designed for control and on/off pur-poses. Temperature range start from -270 °C (cryo) toca. +200 °C, pressure rating ANSI class 150, PN10,PN16, ISO PN20.Use Nelprof code BK Wafer-150 also for Lug designsizing.
