NAF-Check Valves Pressure/Temperature Ratings for liquids, gases, vapours, aggressive fluids and ') without spring 3) Max. Einsatztemperatur bei Ausführung mit Feder + 300 °C.

NAF-Check Valves Pressure Drop Chart The curves given in the chart are valid for water at 20 °C. To read the pressure drop for other fluids the equivalent water volume flowrate must be calculated and used in the graph. The values indicated in the chart are applicable to valves with horizontal flow. With vertical flow insignificant deviations occur only within the range The chart and flow characteristics are available up to and including PN 40. Higher PN increase the zeta values and pressure drops at the same The kvs values decrease accordingly. Equivalent water volume flow Volume of fluid (operating...
