• Import Controls from Modelbuilder

    Hi, I have site data for PRV's in my model. For flow modulated PRV's I have data such as; PRV-1 Pressure Flow 35 m 5 l/s 38 m 10 l/s 41 m 15 l/s 44 m 20 l/s and for the time modulated PRV's I have…
  • Re: PRV control (activating when pump turns off)

    So you have a logical control on the PRVs that says something like "set PRV pressure setting to 105psi when the pump is off"? I think the problem is that the PRV control isn't checked until after the pump goes off - giving you that 0.1hr delay…
  • Control valve response to transient event

    Is there a way to model the response of a control valve to a transient event beyond manually inputting the transient operational pattern? An example would be what happens to a PSV when the transient pressure drops below the pressure set point.
