Modeling a PRV in a steady state analysis
Modeling a PRV in a steady state analysis
(OP)
Hey guys, I'm new to the forum and am in need of some tips here. I am using WaterCAD to model a new water distribution system for a subdivision. The initial results of my model tell me that I need some Pressure Reducing Valves...the only problem is that the PRV's close instantaneously due to the pressures exceeding my controls; thus disconnecting the rest of my system.
Are there any other ways to model PRV's in steady state analysis...Thanks!

Can you change the Cv or Valve size? Maybe you can use a full open 4" valve to simulate a 12" at 25% open or something.

I would check the controls on the prv, It should self modulate to give the desired results. if it is closing, is it backwords? do you have demands on both sides of the valve? is your source stable?
