exploring feasibility of a magnetically actuated valve in a microfluidics system

Kibbel

I'm doing some research into constructing a gate in a microfluidics channel. I have worked out the physics for building a small gate which could be magnetically actuated to begin to move against up to 25 pascals of fluidic pressure. could someone with some experience in microfluidics to tell me what 25 pascals of pressure in a microfluidics channel would mean? as in, is that a feasible number for a force?
