Proportional valve tested at 350 bar, 80lpm has pressure drop 20bar. If the same valve used at 80bar, 80lpm will it have same pressure drop?.Assuming net pressure avialable at inlet pressure port in both case and same oil grade used in both case.

To find the pressure drop in any type of valve, control valve, meter, etc. refer to the manufacturer submittal sheet (cutsheet) and look for the pressure drop amount in valve or device. These are always specified by the valve products' manufacturers.
