do I need to include loss in a surge anticipator valve in TDH?
do I need to include loss in a surge anticipator valve in TDH?
(OP)
I have a dum question, CLA-VAL suggested me to use a 8inch surge anticipator valve for 4167 gpm, as they said the valve only opens when surge occurs, in this case do I need to inlude the loss across the surge anticipator valve, which is really high (30 psi at 4167 gpm)? It sounds like I dont need to included it as the surge anticipator valve only works when pump shuts down during a power failure. as the pump does not need work, it does not need to pump water at all, thank you.

Beware that surge anticipation valves sound great in theory. Having modelled and commissioned these many times as a potential solution I can tell you that they are not the panacea the salesman would have you believe. In addition they are high maintenance. If you dont maintain them they dont work. Refer www.pipingdesign.com. There are a couple of papers there you should read on surge.
If ther salesman has done the surge analysis for you i would be doubly wary as to the results. There is a conflict of interest there.

From you post, it sounds like you do not have much experience with surge analysis. You probably should have an experienced person review your work.
