Abstract:In this peper, the configuration, performance and contamination resistance of servovalve and proportional valve have been compared. The No.704 Research Institute of China Shipbuilding Industry Corporation has developed jet pipe servo proportional valve on the basis of jet pipe servovalve. This servo proportional valve uses prepositive independent jet amplifier, straight feedback spring, external filter and filter-module, improves the anti-contamination capability and reduces cost farther. The performance of the jet pipe servo proportional valve is equal to servovalve, however its contamination resistance is equal to proportional valve, and the cost is only 1/3~2/3 of import servo proportional valve.
Key words: jet pipe servo proportional valve servovalve proportional valve contamination resistance
