Introduction of Sintered Multi-layer Valve Filter Element
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.
Product Features
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.
