High Precision Hydraulic Oil Filter Element for Aerospace & Precision Machinery
Details
Miniature valve body filter elements are typically manufactured via vacuum electron beam welding, with a diameter of less than 20mm (minimum down to 5mm) and a length of less than 100mm.
They are designed for filtering hydraulic oil or gas in precision servo valves within hydraulic and pneumatic control systems. Key advantages include:
High filtration accuracy, excellent strength and rigidity, low flow resistance, and large flow capacity.
High inherent cleanliness, easy installation, stable pore size, and long service life.
Can replace bronze powder sintered filter elements (1st generation valve filters), metal mesh wrapped core filters (2nd generation valve filters), and imported metal wire-wound filters, ensuring more stable and reliable servo systems.
Deep Weld Penetration: Large welding penetration depth, small dimensional tolerance, and high weld strength.
Narrow Weld Seam: Weld width is typically only 1–1.5mm, ideal for manufacturing small-sized filter elements and discs (solving previously insurmountable challenges).
Minimal Deformation: Extremely low deformation rate, high yield rate, and consistent product quality.
Non-oxidizing Welding: Oxide-free welding process with fine weld seams, resulting in aesthetically pleasing components.
High-end Compatibility: Capable of replacing imported products and suitable for military/defense applications.
