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.

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.
Scope of Use

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.
