A permanent magnetic valve with a characteristic of fast response is used for executive components of fuel-feeding control and high-accuracy control systems of an automobile and a rocket engine. By means of a permanent magnet, the characteristics of a magnetic circuit are changed, inductivity of a magnetic valve coil is reduced, and the magnetic valve can produces the fast response to a signal, achieves quick starting and closing and improves a pulse characteristic of an engine and stability of the systems. The permanent magnetic valve comprises a connector, a filter device assembly, the permanent magnet, a casing, the coil, a valve body, an upper gasket, an armature assembly, a lower gasket and a valve seat. The filter device assembly comprises an upper press ring, a filter screen and a lower press ring. The armature assembly comprises an armature, an upper reed, a lower reed, an outer fastening ring, a blocking plate, a pin, an inner fastening ring and a magnetic inducting ring. The valve adopts the permanent magnet to adjust the characteristics of the magnetic circuit, enables current on the coil to be changed fast and enables switching speed of the magnetic valve to be improved remarkably. Resultant force consisting of permanent magnetic force produced by the permanent magnet and spring force can ensure reliable seal of the valve seat.
