Has anyone simulated a Cla-Val surge anticipator (Model 52-03) or surge relief valve (Model 50-01) in Water Hammer? The surge anticipator valve seems straight forward, but I'm not sure what kind of variables to use for time to open, time stays open, or time to close. These are all adjustable settings I believe, so is it trial and error in the model to specify these parameters and then field adjust and recheck in the model? Are there min. values for the valve to open and close?
And the surge relief valve in Hammer doesn't seem to apply to a Cla-Val. The Cla-Vals are hydraulically controlled so I don't believe they specify a spring constant...
Thx
