| Abstract: | The construction,working principle and performance of the twin flapper-nozzle electro-hydraulic servo valve were introduced,and then equations on the static PQ characteristics were achieved utilizing mathematic models.The static flow characteristics of the servo valve were obtained by the experiment.Both the simulation and experimental results indicate that the dual flapper-nozzle servo valve has good flow-current characteristics and strong ability to control small flow rate. |
