Pressure drop chart:
Graph readings apply to water at 68° F (20° C). They result from measurements on valves installed in horizontal pipes. For installation in vertical pipes insignificant devitations occur in the partial opening. In order to determine pressure losses for other media the equivalent water flow has to be calculated before.
