TīmeklisKv is the volume of water in cubic meters that flows through a valve per hour at a pressure drop of 1 bar with a fully open valve. For example, a Kv of 20 means that the valve has a flow capacity of 20 cubic meters per hour (m³/h) when there is a pressure drop of 1 bar across the valve. TīmeklisLe fabricant de raccords Mason-Neilan (MA, USA) a introduit à la fin des années 40 le coefficient de débit cv.
