HENGKO delivers precision porous metal flow restrictors that provide a reliable and economical replacement for small control valves. A porous metal flow restrictor is a passageway with many small holes that creates a large number of random streams. Flow restrictors are suitable for use in gaseous as well as liquid environments. For liquid environments special flow restrictors are available. The flow restrictors are available in stainless steel, Inconel, and Monel for optimal protection against corrosion.
The flow restrictors are available in a wide range of porosity to ensure the perfect flow rate for the desired applications. A porous metal flow restrictor has a porous surface that is 500 times as large as that of similar passages without porous material. The advantage is that a laminar flow will be created with a minimal disturbance in speed, pressure, and temperature as compared to an orifice.
