Sintered Porous Metal - High Purity Flow Restrictors uesd in high-flow C-Seal configuration gas systems / flow setting device for gas processes – HENGKO

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 an 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.

FAQ

Q1. Why porous metal?

-- Filtration systems using sintered metal media for gaseous, solid and liquid separation have proven to be an effective and  efficient alternative to other separation methods that can be vulnerable to pressure peaks, high temperatures and/or corrosive environments. Sintered metal is highly efficient in removing particulates, delivers a reliable performance, is easy to clean and has a long life in comparison with leaf filters, filter bags and plate and frame filters.  

Q2. What kind of structures can you make?

-- We make various types like disc, tube, cup, cartridge, plate, etc.

Q3. Do you provide customized services?

-- Yes, of course.

Q4. If samples available?

--  Sure, no problem.
