1. Dedicated motor, characterized by strong overload capacity, large starting torque, small moment of inertia, short-time and intermittent work
2. Deceleration mechanism to reduce the output speed of the motor
3. The stroke control mechanism is used to adjust and accurately control the opening and closing position of the valve
4. Torque limiting mechanism, used to adjust the torque (or thrust) and make it not exceed the predetermined value
5. Manual and electric switching mechanism, interlocking mechanism for manual or electric operation
6. The opening indicator is used to show the position of the valve during the opening and closing process.
