Protecting doors and frames

By controlling the speed and force with which doors close, door brakes help protect the door and frame from damage. This practice can extend the lifespan of both the door and its hardware, ultimately saving you money by reducing the need for repairs and replacements. Imagine the peace of mind that comes with knowing your beautiful wooden door won’t be damaged by a careless slam.

How do hydraulic door closers work?

Understanding how door closers function can simplify the adjustment process and lead to better outcomes. Now, let’s examine the main parts and their functions:

Hydraulic fluid
The core component of hydraulic door brakes is the hydraulic fluid. As the door opens, this fluid is forced through a series of valves inside the stopper. These valves control the speed and resistance of the door’s movement, ensuring it closes smoothly and at a controlled pace.

Springs

Inside the hydraulic stopper, a spring compresses when the door opens. The stored energy is subsequently discharged to shut the door. The tension of the spring can be adjusted to control the closing speed and force.

Valves and adjustment screws

Door stoppers are equipped with various valves and adjustment screws. These allow you to fine tune different aspects of the door’s closing action, such as the speed, backcheck, and latching speed. 

Arm mechanism

The arm mechanism attaches the hydraulic stopper to the door. The arm design may vary, including regular, parallel, or top jamb arms, each impacting the closing force and adjustment methods.

Types of door stoppers

There are several types of door closers, each designed for specific applications and door types. Understanding these can help you choose the right stopper and make proper adjustments.

Surface mounted door stoppers

Mounted door stoppers are widely favoured for their ease of installation and durability, providing effective protection against wall damage caused by door handles. These stoppers are straightforward to install and adjust, making them a popular choice for both residential and commercial settings.

Floor spring door stoppers

Installed in the floor beneath the door, floor spring door stoppers are commonly used for heavy doors such as glass doors in commercial buildings. They offer a high degree of control and are often used in conjunction with other door hardware. These stoppers are particularly suitable for doors that experience heavy use and require robust support.

Overhead concealed door stoppers

These types of door stoppers are installed in the header of the door frame, providing a concealed look similar to floor spring stoppers. They are often used in storefronts and other applications where a clean, unobtrusive appearance is desired. These stoppers are ideal for environments where both functionality and aesthetics are paramount.

High efficiency door stoppers

Designed for doors that require a higher degree of control and efficiency, high efficiency door stoppers often feature advanced hydraulic systems and adjustable settings. They are suitable for high-traffic areas and doors that experience significant use. These stoppers are engineered to provide superior performance, making them an excellent choice for demanding environments.

Adjusting a hydraulic door stopper: Step-by-step guide

Now that you have a solid understanding of the purposes and workings of hydraulic powered door closers, it’s time to dive into the adjustment process. Follow these steps to ensure your door operates smoothly and efficiently.

Step 1: Identify adjustment screws

Most door closers have at least two adjustment screws, one for controlling the closing speed and another for the latching speed. Some models may also have additional screws for backcheck and delayed action. Identifying these screws is the first step in the adjustment process.

Step 2: Closing speed adjustment

The closing speed adjustment screw controls the speed at which the door closes from fully open to about 10 degrees from closing. Rotate the screw to the right to reduce the closing speed and to the left to increase it. This simple adjustment ensures a gentle and secure door closure.

Step 3: Latching speed adjustment

The latching speed adjustment screw controls the speed of the door in the final few inches of closing. Adjust this to ensure the door closes securely but without slamming. Similar to the closing speed, turn the screw clockwise to slow it down and counterclockwise to speed it up. Proper latching speed adjustment is crucial for maintaining both security and noise reduction.

Step 4: Backcheck adjustment

If your door stopper has a backcheck feature, this adjustment controls the resistance the door encounters when opened forcefully. This is particularly useful for preventing damage in high-wind areas or where doors are often opened abruptly. Turn the screw clockwise to increase resistance. This adjustment helps protect the door and frame from sudden impacts.

Step 5: Delayed action adjustment

Some hydraulic stoppers have a delayed action feature, allowing the door to stay open for a longer period before beginning to close. This adjustment can be beneficial in healthcare environments or for ensuring ADA compliance. Modify it by adjusting the screw to achieve the desired delay. Delayed action adjustments are ideal for environments where doors need to remain open for extended periods.

Step 6: Test and fine tune

After making initial adjustments, test the door’s operation by opening and closing it several times. Fine-tune the screws as necessary to achieve smooth and controlled motion. Testing and fine tuning ensure that the door operates exactly as desired, providing optimal performance.
