Inherent vs installed valve characteristics
WebbRemember, the inherent curve exclusively describes losses through the valve itself. For the installed curve, the valve only makes up one component of the system’s pressure … Webb6 okt. 2009 · A valve having Equal percentage characteristic (inherent) will produce equal % increments in Cv for equal % increments in the valve lift. The % increment in Cv depends on the rangeability of the valve. Valves with high rangeability produce higher % increments in flow rate. The relation between the valve lift (%) and the Cv at that lift is …
