Fluid viscosity … WebCv (Imperial) = Kv x 0.962 658 Cv (US) = Kv x 1.156 099 AV = 2.88 x 10-5 CV (Imperial) The flow coefficient, KVS for a control valve is essential information, and is usually stated, along with its other data, on the manufacturer’s technical data sheets. how to stop feeling so hungryWebThe effect of viscosity of fluids other than water should be considered when selecting the valve, as increased viscosity of fluid is reducing the valve capacity. how to stop feeling so angry

"The flow coefficient of a device is a relative measure of its efficiency at allowing fluid flow. It describes the relationship between the pressure drop across an orifice valve or other assembly and the corresponding flow rate. Mathematically the flow coefficient Cv (or flow-capacity rating of valve) can be expressed as : where: " - Hight viscosity impact to cv of control valve

WebFeb 2, 2024 · Viscosity is responsible for erosion-corrosion of the valves used for viscous fluid service. When clogging occurs around valves, more foreign material and debris accumulates within the valve body. Moving viscous fluids past the valves at high process speeds accelerates the corrosive action of the particles. WebDec 19, 2024 · 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. Table …

WebThe Cv flow coefficient of a control valve can be calculated from the flow rate and the pressure drop through the valve. For liquids other than water the ratio of the fluid density to the density of water must also be used in the calculation. Where: Cv = flow coefficient Q = flow rate in US gpm ∆P = pressure loss in psi across the valve WebThe first impact that may come to mind is a larger orifice – and it’s correct. The size of the orifice can benefit flow through and directly relates to the volume of your valve. However …
