High Purity Flow Restrictors uesd in high-flow C-Seal configuration gas systems / flow setting device for gas processes

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.

High Purity Flow Restrictors used in high-flow C-Seal configuration gas systems/flow setting devices for gas processes

Product Description

1. Accurate pore size, uniform, and even-distributed apertures. Pore size range: 0.1um to 120 micron;

2. Good breathability, fast gas & liquid flow rate, and uniform divergence.  it is far superior to other peer products with the optimization of special processes in HENGKO.

3. Good filtration dustproof and interception effect, high filtration efficiency. The pore size, speed of the flow, and other performances can be customized as requested;

4. High supporting load capacity, no need to use other auxiliary supports, can be directly used as structural elements;

5. Stable structure, particles are tightly bound without migration, almost inseparable under harsh environments;

6. High fatigue strength and impact stress, high pressure resistant, suitable for applications with a high-pressure difference and flow rate. Sintered porous stainless steel filter elements for long-term usage under high-pressure fluid (40mpa) conditions are available;

7. Resistance to high temperature and heat shock. HENGKO stainless steel filter elements can operate at 600 degrees Celsius, can withstand high temperatures even in oxidized atmospheres;

8. Excellent functions of separation and noise reduction as a result of special multidimensional honeycomb nested capillary structure;

9. Different from other peers, HENGKO stainless steel filter elements haven't been corroded in a variety of environments. The performances of anti-corrosion and rust-proof and are close to dense stainless steel products;

10. More than 10K product sizes and types to choose from, customizable as needed for stainless steel filtering products with multiple complex structures;

11. Tiny diameter( 5-20 mm), the length of a long filter tube can be up to 800 mm;

12. The processable dimension for the plate filter can be up to L 800 * W 450 mm;

13. The maximum diameter for a disc filter can be up to 450 mm;

14. Exquisite product appearance will upgrade your product level and image greatly as apparent parts;

15. A variety of cleaning methods are available, and strong regeneration ability after reverse cleaning has a long service life.
