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.
