Electro-hydraulic servo valves are widely used in power plant,steel plants and many processing plants, such as steam turbines, injection molding machines, and die-casting machines. They are now widely used in precision hydraulic systems. Electro-hydraulic servo valves include servo pressure valves and servo flow valves. The brands we often see in the market are BOSCH REXROTH, MOOG, Parker, China’s 609, 704 and so on.
Electro-hydraulic servo valve is a key component in electro-hydraulic servo control, so the maintenance of electro-hydraulic servo valve is particularly important! Oil is the blood of equipment. When conditions permit, the contamination degree of the working fluid should be checked regularly. Protecting the cleanliness of the oil is a crucial work. In the maintenance and after-sales of the proportional valve of the electro-hydraulic servo valve, it is necessary to replace the filter element and other accessories regularly.
The filter elements in the servo valve are also called micro-valve filter elements due to their small size. The micro-valve filter element generally refers to the filter element welded by vacuum electron beam, and it can also refer to the filter element whose diameter is less than 20mm, the minimum diameter can reach 5mm, and the length is less than 100mm. It is commonly used in the filtration of hydraulic oil or gas of various precision servo valves in hydraulic and pneumatic control systems. It can replace the bronze powder sintered filter element (the first generation valve filter), the skeleton-coated metal mesh filter element (the first generation valve filter) and the imported wire wound filter element, making the servo system more stable and reliable, and has been widely used in aerospace, Hydraulic machinery, precision machine tools, automatic control and other fields.
Our servo valve filter element characteristics:
1. The welding penetration is large, extremely small tolerances, welding seam strength is high;
2. The welding seam is narrow, generally only 1-1.5mm, which is very suitable for the manufacture of small-sized filter elements (solving the original impossible problem);
3. The deformation is small, the pass rate is high, and the quality is stable;
4. Because the welding is not oxidized, the welding seam is fine, and the components are beautiful;
5. It can replace brands and used military products.
In addition to conventional models, non-standard processing and customization are also acceptable.
