Analysis results show that the torque motor linearity mainly by Km/Ka decision, should reduce bit parts load inertia Ja, increasing torsional axis bit of mechanical spring stiffness kas, to improve bit the inherent frequency omega m, Double jet flapper valves in zero near tiny within the scope of the pressure - flow characteristic curve of linear good, with the increase of zero leakage expense, increased pressure gain, physical symmetry makes for temperature and oil supply pressure changes arising from the zero drift decrease.
