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.

Adjust the valve if the screw tightening (clockwise adjustment) is to slow down the speed, that is, closing the door close the door to adjust the power. If the valve screw loose (counterclockwise adjustment) is the speed becomes faster, that is, increase the closing door closing force. Adjust the amplitude must be controlled in a small range, and each adjustment are tested door fan strength is appropriate, if the amplitude is too large may screw off, resulting in door closers oil spill.

This installation method is suitable for wide door frame, there is enough space to install the door closer. Compared with the standard installation, this installation method is suitable for opening doors such as walls and other obstacles. This type of installation has a greater closing force and is suitable for larger and heavier doors.

Adjustment method and precautions: (1) generally in the side of the door closer to the side of the adjustment valve is marked 1.2, speed 1 block is to adjust the door opening angle from 90 degrees to 20 degrees between the closing speed, speed 2 is to adjust the door opening angle from 20 Degrees to 0 degrees is the door completely closed the speed of the trip. (2) When adjusting the valve screw tightening (clockwise adjustment) is to slow down the speed, that is, the door closer to the door to adjust the power. (3) If the valve screw loose (counter-clockwise adjustment) is the speed becomes faster, that is, increase the closing door closing force. Adjust the amplitude must be controlled in a small range, and each adjustment are tested door fan strength is appropriate, if the amplitude is too large may screw off, resulting in door closers oil spill.
