Door closer produced by door closer supplier is commonly used in commercial buildings such as offices, hotels, and hospitals. The door closer works by using a combination of springs and hydraulic fluid to control the speed at which the door closes.

By turning the screw, the user can increase or decrease the amount of hydraulic fluid that is allowed to flow through the valves, which in turn affects the speed at which the door closes.

Overall, the door closer provides a convenient and safe way to automatically close doors, without the need for someone to manually close them.
