Product Details

MOOG A67999-100 is a field-replaceable pilot stage filter disc, designed for MOOG G631, D661, D630 series and other common electro-hydraulic servo valves. This moog filter disc adopts brass frame and folded stainless steel filter mesh structure, it can effectively trap tiny solid particles and impurities carried in hydraulic fluid before entering the torque motor and nozzle-flapper pilot stage assembly. It prevents blockage of the nozzle and flapper components, eliminates control deviation and unstable valve action caused by contamination, protects the ultra-precise internal parts of the servo valve, reduces unexpected system downtime and extends the whole service life of servo valves. The filter disc features compact circular dimension, stable filtration accuracy and excellent pressure resistance, it maintains consistent filtration performance under mechanical vibration and temperature fluctuation in industrial hydraulic systems. It is a standard maintenance spare part and can be replaced easily during regular servo valve overhaul without complex disassembly tools. The filter mesh and brass frame have good corrosion resistance, compatible with mineral oil and fire-resistant hydraulic fluid. This servo valve filter disc is widely applied in material fatigue test benches, aerospace structural loading test systems, automotive component durability test equipment and gas turbine hydraulic control systems. It is an essential consumable to maintain stable operation of closed-loop hydraulic control systems and guarantee the control precision of MOOG servo valves.
