Lower Resistance,Large Flow Capacity 38um Multi-Layer Valve Filter
Element Used For Filtration Of Hydraulic Oil And Gas
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.

FAQ
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.
