Product Details

MOOG A67999-065 is a field-replaceable pilot stage filter disc, specially designed for MOOG series electro-hydraulic servo valves. This filter disc adopts brass frame and folded stainless steel filter mesh structure, which can effectively intercept tiny solid particles and impurities in hydraulic fluid before entering the torque motor and flapper nozzle pilot stage. It can protect the precision machined internal components of the servo valve, prevent nozzle blockage and abnormal control deviation, reduce unexpected downtime and extend the service life of the servo valve. The filter disc features compact circular layout, stable filtering accuracy and good pressure resistance, it can maintain stable filtration performance under vibration and ambient temperature fluctuation in industrial hydraulic systems. It is easy to replace during regular valve maintenance, no complicated tools are required for disassembly and installation. The filter material has excellent corrosion resistance, compatible with mineral oil and fire-resistant hydraulic fluid. This servo valve filter disc is widely used 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 spare part for MOOG servo valve routine maintenance to guarantee stable operation of closed-loop hydraulic control systems.
