Orifice flow restrictor

Mott Porous Metal Flow Control Devices Customized to Your Flow The most reliable and durable means of controlling fluid flow. Mott Customized Flow Restrictors, Flow Orifices, and Flow Plugs Mott precision porous metal flow restrictors and flow orifice devices are reliable, cost-effective replacements for standard orifices, capillary tubes, and micrometering valves. A porous metal flow restrictor or flow plug is, in effect, a multiple orifice device with many very small holes, creating a vast number of random pathways. Typically, a Mott porous metal flow restrictor or orifice device has a porous surface area 500 times that of an equivalent drilled orifice. Less friction means longer life – Mott flow restrictors,flow orifices and flow plugs 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 and orifice devices incur less wear, and last longer. The most repeatable performance over time – As gas and particulate erode and enlarge a drilled orifice, flow increases in proportion to the square of the increase in size. Mott porous metal material resists such physical change because of the lower velocities and virtual absence of erosion, resulting in more consistent, reliable flow control. Clog-free operation – A single grain of foreign matter can easily clog a drilled orifice or capillary tubing. Mott flow restrictors, flow orifices and flow plugs 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.
