(1) The unloader adopts the principle of planetary rotation  the input and output are on the same axis  and it has the uniqueness of being directly integrated with the motor  so the structure is compact and beautiful.

New concept  small size  lightweight.

(2) unloader operation is reliable and stable  low noise  low failure  long life  toothed joints with ductile iron and bearing steel  etc.. Good performance  high wear resistance.

(3) bearing  gear box  away from the valve body  to avoid the impact of high temperature dust  the front and rear end caps have good sealing performance  prevent the leakage of dust  extend the motorized parts  lubrication system

Service life.

(4) The unloader has strong overload capacity  low impact moment of inertia  and is suitable for frequent start and reverse rotation.

(5) If users need special specifications  unloaders such as motors and sprocket drives can be made.
