The most reliable means of restricting gas flow.
Mott precision porous metal flow restrictors are reliable, cost-effective replacements for orifices, capillaries, or micrometering valves. A porous metal flow restrictor is, in effect, a multiple orifice device with many very small holes, creating a vast number of random pathways. Typically, a Mott porous metal restrictor has a porous surface area 500 times that of an equivalent orifice.
Less friction, longer life – Mott flow restrictors channel gas through hundreds of pores instead of just one, reducing gas exit velocity. Because gas and particulate move slower through the element, porous metal flow restrictors incur less wear, and last longer.
Repeatable performance – As gas and particulate erode and enlarge an orifice, flow increases in proportion to the square of the increase in size. Mott porous metal resists such physical change because of the lower velocities and virtual absence of erosion, resulting in more consistent, reliable flow restriction.
Clog-free operation – A single grain of foreign matter can easily clog an orifice. Mott media, on the other hand, can tolerate a significant build up of particulate before flow is affected the low gas velocity and high media surface area enable gas to find its way around obstructions.
