120um SS316L Welded By Vacuum Electron Beam Multi-Layer Valve
Filter Element Longer Service Used In Aerospace
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.

Product Advantages
1.High filtration accuracy, stable aperture, small pressure loss,
aperture does not change with pressure. It can effectively remove
suspended matter and particles, with good filtration precision and
purification effect.
2.High porosity, uniform and smooth pores, small initial
resistance, easy backwash, strong regeneration ability, long
service life, especially suitable for fluid distribution,
homogenization treatment and other occasions requiring high
uniformity.
3. High mechanical strength, good rigidity, good plasticity,
oxidation resistance, corrosion resistance, do not need additional
skeleton support protection, easy installation and use, easy
maintenance, good assembly, can be used for welding, bonding,
processing.

FAQ
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:Classification of sintered cartridge
A:First, according to the material, there are metal sintered
cartridge and non-metal sintered cartridge. Metal sintered
cartridge is mainly stainless steel series as the main
material.There are also titanium rod sintered cartridges and monel
sintered cartridges made of special metals. Non-metallic sintered
cartridge has activated carbon as the material,
carbon sintered cartridge; powder sintered cartridge and copper
powder sintered cartridge made of metal powder; pe sintered
cartridge made of polymer.
Second, according to the function, there are surface filtration
sintered cartridge and depth filtration sintered cartridge. Like
sintered mesh cartridge is surface filtration sintered cartridge.
The general surface filtration type is the sintered cartridge with
sintered mesh as the material, because the sintered mesh is the
surface filtration. And like powder sintered, the sintered
cartridge with fibers, particles and granules as materials such as
sintered felt are depth filtration sintered cartridges. For
example, copper powder sintered cartridge, activated carbon
sintered cartridge, sintered felt cartridge, etc.
