Mott precision porous metal flow restrictors are reliable, cost-effective replacements for mass flow controllers, orifices, capillaries, or micrometering valves. Product designers can be assured of a constant gas flow at a given gas pressure without having to worry about clogging and without having to design for wide variations in flow.

When compared to a drilled orifice, these gas flow restrictors channel through thousands of pores instead of just one, reducing gas exit velocity and resulting in a more laminar flow. In addition, because the gases move through the myriad of pores, porous metal flow restrictors are virtually impervious to erosion or wear, retaining the original calibration almost indefinitely.
