Understanding How A Commercial Door Closer Works
A commercial door closer is a mechanical device that works by applying pressure to control the speed and force at which a door closes. This mechanism consists of two valves that control the speed and force of the door closer. One valve controls the speed of the door closer, while the other valve controls the force or resistance applied by the door closer. Understanding how this mechanism works is essential to adjust your door closer correctly.
Determining The Type Of Commercial Door Closer You Have
Before making any adjustments, knowing the type of commercial door closer you have is essential. There are two types of door closers available: pneumatic and hydraulic. Pneumatic door closers operate using air pressure, whereas hydraulic door closers operate using fluid pressure. Once you've identified what type of closer you have, you're one step closer to correcting your problem.
Steps To Adjust A Commercial Door Closer
Finding the right way to adjust a commercial door closer can be stressful, but with these simple steps, you'll be done in no time.
Step 1: Identify the control valves
You will need to identify the two adjusting valves present on the door closer. These include the closing speed valve, regulating the speed at which the door closes, and the latch speed valve that controls the speed when the door is coming up to close.
Step 2: Adjust the speed valve
After identifying the closing speed valve, you can slowly adjust it clockwise until the door speeds up, or anticlockwise until the door slows down. Make sure to do small, gradual movements until you reach your desired speed.
Step 3: Adjust the latch speed valve
The latch speed valve determines how fast the door will travel from an open to closed position in the final few inches. Adjust it in the same way you did with the speed valve.
Step 4: Apply tension adjustments
If you feel like the resistance on the door closer needs fine-tuning, you can make tension adjustments through a screw located under the rubber covering. Tighten the screw to add force or loosen it to reduce the force. Remember to check the manufacturer's instruction for precision.
Step 5: Observe the door operation
After making all changes, observe the door's movements to ensure that it operates smoothly and safely. If the door still doesn't perform correctly, we recommend that you consult a professional.
In Conclusion
Adjusting a commercial door closer can be quite challenging, but by following the correct steps and understanding its operation, you'll have a safer and smoother opening and closing mechanism. So next time you find yourself struggling with a commercial door, use our guide to adjust the closer properly. Remember always to put safety first.

The closing force adjustment is the most critical aspect of adjusting a door closer. Adjusting the closing force determines how much force is needed to close the door and latch it shut. If the closing force is too weak, the door will not latch shut properly, while if it’s too strong, the door may slam shut forcefully. Therefore, you need to adjust the closing force correctly.
Step 4: Adjust the Latching Speed
The latching speed determines how fast the door closes in the last few inches of travel towards the frame. Adjusting the latching speed prevents doors from slamming shut forcefully and ensures that the door latches into place securely.
Step 5: Adjusting the Sweep Speed
The sweep speed adjustment controls how fast the door closes in the first half of its travel. Therefore, it’s essential to adjust the sweep speed as it affects how fast the door swings after opening and reduces the pressure against the frame.
Step 6: Adjusting the Backcheck
Backcheck is the resistance offered by the door closer as the door swings open past 75-80 degrees. The backcheck adjustment controls how much resistance your door closer offers when the door is pushed or pulled open beyond its regular opening length, preventing damage to both the door and the closer hardware.
Step 7: Test the Door
After finishing adjusting the door closer, test the door fully to see if it operates smoothly and shuts correctly. Make sure that the door latches properly and doesn’t slam shut forcefully. If this is the case, go back to re-adjust the door closer based on the adjustments identified earlier.
