Sintered multi-layer valve filter element is welded by vacuum electron beam,used for filtration of hydraulic oil and gas in hydraulic and air control system.The features of it are high precision,good rigidity,lower resistance,large flow capacity.And also it has advantages of cleanness,easy use,stable filtering aperture and longer service,it is alternative for sintered bronze powder filter element(the first generation valve filter),and metal mesh filter supported by framework(the second generation valve filter)and even imported wire wound filter element ,to make the serve system more stable and morereliable.It is widely used in many fields such as aerospace,aviation, hydraulic machine,precision tool and automatic control.
1. Large welding penetration, small error and high weld strength;
2. Narrow weld, generally only 1-1.5mm, very suitable for small size filter element filter plate manufacturing (solve the original impossible problem);
3. Small deformation, high qualified rate, stable quality;
4. Because the welding does not oxidize, the weld is fine, the element is beautiful;
5. Can replace imported and used for military products.

Q:Are you trading company or manufacturer?
A:We have our own factory and production line. Everything is very flexible, no need to worry about additional costs. At the same time, quality can also be guaranteed.
Q: What parameters need to provide for the design of the filter element?
A: Length, width, height, material, diameter, precision, connection method, etc. If there are other necessary parameters, please explain together.
Q:What does the mesh of the filter indicate?
A:The mesh of the filter refers to the particle size or coarseness of the material, but also refers to the number of holes in an area of 1 inch x 1 inch, that is, the number of holes in the screen.The number of mesh holes through which the material can pass is defined as the number of mesh. For example, 200 mesh is the material can pass through a screen with 200 mesh holes in 1 inch x 1 inch. The higher the mesh number, the finer the particle size of the material, and the smaller the mesh, the larger the particle size of the material.
