I have ran a pump system, where pump and valve are selected as "design". I understand that this is also not possible in the local version of fluid flow. Its either the pump curve is specified, or the control valve curve is specified (i.e. created in database both instances). Normally in pump hydraulics in excel spread sheet, we usually assign 70 kPa as minimum pressure drop of a valve, to estimate the pump head (or size the pump).
