| Abstract: | On the basis of analyzing the virtues and the defects of the distributive valve, which was drove by a stepping motor in hydraulic turbine governor, we developed a new two stage electro hydraulic digital servo valve. It had great ability to resist oil pollution and interference. Such valve has low influence by mechanical unknown quantity and low drive torque and has eliminated mechanical dead region. So it could be used in the system with high pressure and big flow. |
