A novel design and research for an electromagnetic valve actuator with permanent magnets

Valve actuator is a critical component of the electromagnetic valve in the pneumatic steering gear. By controlling the action and release of the actuator, the gas circuit can be switched, thus to control the attitude adjustment of the missile. The traditional actuator is solenoid structure. In order to satisfy the demand of saving energy, lowering the driving power of the coil and providing enough output force, a new structure of actuator with permanent magnets is presented here.
