Product Details

MOOG A67999-200 is a field-replaceable pilot stage filter disc, designed as maintenance spare part for MOOG electro-hydraulic servo valves. This moog filter disc adopts brass outer frame and folded stainless steel filter mesh structure, it can trap large solid particles and impurities inside hydraulic fluid before the fluid enters the torque motor and nozzle-flapper pilot assembly. It effectively avoids nozzle clogging, unstable control signal and abnormal valve movement caused by fluid contamination, protects ultra-precise internal components of servo valves and extends the service life of servo control units. The filter disc features compact circular structure, stable pressure resistance and good vibration resistance, it can maintain consistent filtration performance under continuous vibration and temperature fluctuations in industrial hydraulic systems. It can be quickly disassembled and replaced during regular servo valve overhaul, no complicated installation tools are required. The brass frame and stainless steel mesh have 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 a necessary consumable for daily maintenance of closed-loop hydraulic systems to keep MOOG servo valves running stably and maintain the control accuracy of hydraulic equipment.
