Hydraulic Flow Regulator

[Yehah]

I’m in the process of designing a fluid flow regulator based on the long proven concept of flow through an orifice. However, I want to be able to adjust the flow rate from a remote location. I'm thinking of using multiple orifices in the regulator and adjusting it by selectively sliding a sleeve over them to open or close each one. Since the standard equation for flow through an orifice includes a K factor based on the shape of the orifice, I'm wondering if the inclusion of multiple orifices placed in parallel between the high pressure and low pressure flow regime will have a dramatic effect on this K factor. If anyone can help, it would be greatly appreciated.

Why don’t you buy an off shelf electric proportional flow control?

Why not use a valve?

You should have no problem doing it your way and as for the K factors you can get empirical results very reasily without regard to the theoretical K factor which are not accurate anyway.
