4, the closing force can be adjusted - can be used in the door with a wide range of doors on a wide range of different doors to install, and because of environmental reasons to close the door more resistance. Random stepless adjustment can be satisfied with the closing force, especially in the coastal city, travel and other affected by the wind and closing resistance (the door of the force) often change the place.
5, damping reset function temporary shutdown performance (vertical door closers) - in the open any angle, turn off the speed control valve should be able to temporarily suspend the damping reset function.
6, safe and fast super damping off performance (vertical door closers) - in the process of closing any angle suddenly exert force, should be able to quickly and safely shut down.
7, the use of the environment: fire and fire requirements in the winter 35 ° under the premises of the anti-freeze requirements.
