Flow kv
WebOct 21, 2014 · The most common 15-kV voltage is 12.47 kV, which has a line-to-ground voltage of 7.2 kV. The dividing line between distribution and subtransmission is often gray. Some lines act as both subtransmission and distribution circuits. A 34.5-kV circuit may feed a few 12.5-kV distribution substations, but it may also serve some load directly. 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 …

WebKv is the flow of water expressed in m3/hr., at 15 Deg C passing at a pressure difference of 1 bar. The flow factor Kv is the most critical parameter. It characterizes the flow through a valve. Sometimes, we use Kv coefficient in place of Cv. There is a certain relationship between Cv and Kv. WebFor a specific control valve, flow coefficient Cv/Kv is determined experimentally by control valve manufacturers, and you can found it in manufacturers technical specifications. They express coefficient Cv/Kv as the flow rate of water in g.p.m. [m3/h] for a pressure drop of 1 psi [1 bar] across a flow passage [flow coefficient: Cv-imperial, Kv ...
WebThe flow rate value can be determined using a formula; the larger the value, the higher the flow rate will be through the valve at a given pressure drop. Flow rate is expressed as Cv or Kv, depending on the system of measurement being used (imperial or metric, respectively). The minimum required Cv value is often listed in a valve’s product ...
