Cv and Kv relationship are very important for valve sizing and fluid flow rate. The flow coefficient Cv is the valve flow coefficient. Flow coefficient Cv and its metric unit Kv are useful for measuring the valve capacity. In other words, Cv and Kv is a useful parameter for calculating the size of the valve and fluid flow rate. The other names of the flow coefficient are the valve capacity constant or valve flow coefficient
Classification of Control Valves: We can classify the Control valves based on the application, function, motion, port size, and failure states. According to the classification … Read more
