Mini-servo valve sintered filter element, all stainless steel welded filter element

The micro-valve filter element generally refers to a filter element which is welded by vacuum electron beam, and can also be a filter element having a diameter of less than 20 mm, a minimum diameter of 5 mm and a length of less than 100 mm. It is commonly used in hydraulic and pneumatic control systems for various precision servo valve hydraulic oil or gas filtration, with high precision, good strength and rigidity, low resistance, large flow, high cleanliness, easy to use, stable filter holes, long service life It can replace the bronze powder sintered filter (first generation valve filter) and the skeleton-coated metal mesh filter and the imported wire wound filter to make the servo system more stable and reliable. It has been widely used in aerospace, hydraulic machinery, precision machine tools. , automatic control and other fields.

Product Features:

1, the welding penetration is large, the error is small, and the weld strength is high;

2, the weld is narrow, generally only 1-1.5mm, very suitable for the manufacture of small-size filter cartridges (solving the original impossible problem);

3, the deformation is small, the pass rate is high, and the quality is stable;

4, since the welding is not oxidized, the weld bead is fine and the components are beautiful;

5, can be used to replace imports and for military products.

Vacuum electron beam welding sintered mesh filter element

This kind of filter element uses stainless steel sintered mesh as the filter material, which is rolled and welded by vacuum electron beam. The width of the weld is only 1~1.5mm, and the width to depth ratio of the weld is the best among all welding processes, and the welding process does not oxidize.

Product Features:

1. Stable mesh, accurate filtering accuracy, up to 1um;

2. High dimensional accuracy, can be welded with the end into various sizes and shapes, beautiful appearance;

3. Large flow rate, renewable cleaning and repeated use, long life;

4. High strength, can withstand high pressure.

Applications:

Various servo valves:

hydraulic control servo valves, electro-hydraulic servo valves, proportional servo valves, MOOG servo valves, two-stage electro-hydraulic servo valves, three-stage electro-hydraulic servo valves, single-nozzle flapper servo valves, double-nozzle flapper Type servo valve, spool type servo valve, jet tube type servo valve, deflection plate jet type servo valve, position feedback type servo valve, load pressure feedback type servo valve, load flow feedback type servo valve, electric feedback type servo valve, dynamic Iron servo valve, moving coil servo valve, flow servo valve and pressure control servo valve, etc.
