• ### Sizing Needle Valves Physics Forums

2014-8-13 · I am trying to size a needle valve to make sure that it can allow the required flow rate at the fully open position (0.025 m 3/s). For a given Cv you should be able to calculate the maximum flow rate through the needle valve provided that you know the temperature of the gas and the pressure drop across the valve but my problem is that I do not know what the outlet pressure of the needle valve
