DRV Selection Calculations
DRV Selection Calculations
(OP)
Dear All,
We have designed a chilled water system and we have used Double regulating valves in this system now the client is requiring selection calculations of DRVs.
I need to perform DRV selection calculations, can use this formula Kv = Flow Rate (m3/h) / Δ P (Bar) , If yes how can i calculate Pressure Drop? for this ??

that way you reach hydraulic authority of about 0,5,. which enables good regulability. that's very basics.
