Beschreibung

DN 15 - 100 PN 6 - 16 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. standard seal-type: metallic elastic seals: valve plate - option O-ring / NBR (water, mineral oils, heating oil) -30 bis 90°C / EPDM (hot water, steam) -50 bis 140°C / FKM (mineral oils, fuels) -25 bis 200°C / PTFE (almost all materials) -190 bis 200°C, considering using limits of valves
