What is a door closer?

Door closers are devices that allow doors to be closed securely. They are essential when it is necessary to ensure, always or in the event of a fire, a controlled closure . In fact the main purpose of a door closer is to regulate the closing of the door.

A common door closer is composed of several parts that can vary depending on the model: a die-cast aluminum housing, the spring, the piston, the adjusting screws (commonly called valves), the gears, the needle bearing, a rubber seal and finally the latches.

Door closer spring: the mechanism for adjusting the closing of the door

The door closer mechanism is based on the spring of the door closer itself which, when the door is opened, is squeezed. As the spring is squeezed it accumulates the energy needed to close the door when needed. Gears and ribs move the piston, while the oil flows through the internal channels in the free part of the door closer body. During the return phase of the spring, the spring straightens and the door closes softly.

Door closer adjustment: our advice

Adjusting a door closer is a relatively simple process and can be safely done by hand. Adjustment of the door closer should be done 1-2 times a year, based on the number of uses per day. It may be necessary to perform an extraordinary adjustment even in the event of small malfunctions, especially during the change of season. In fact, in summer and winter the climatic conditions change and therefore also the state of the oil inside the door closer.

The adjustment of a door closer must be carried out according to the type of door closer itself. In fact, there are overhead door closers on the market that work on the upper part of the door and floor door closers that block the lower part of the entrance.

To adjust an overhead door closer (located at the top of the door) we recommend that you correctly adjust the different screws and valves located on the housing panel. Overhead door closers are mounted at the top of the sash, so it shouldn't be too difficult to make these adjustments.

The adjustment of the floor door closers , almost invisible to visitors, takes place by applying regulating mechanisms.

How to decrease the closing force of the door closer?

After installing a door closer it may be necessary to make a further additional adjustment. This is to avoid making an effort when opening the door. Just release the valve slightly to allow for easier movement.

This valve can be positioned at the end or on the front side of the door closer, depending on the model. To understand without any doubt where it is, just look at the door closer reference manual where the manufacturer clearly indicates all the positions of the components and elements of the closing mechanism.

How to leave the door closer in the open position?

Sometimes it can be useful to leave the door in the open position . The door closer must therefore be adjusted to the open position, to be maintained for a long period. In some door closer models there is a special function to keep it open: to activate this mode, the door must be opened by about 90 degrees and then the appropriate lock must be closed. After these simple operations, the door leaf can be left open to the adjusted degree.

When you want to close the locked door, you just have to pull it towards you, deactivating the door closer lock. The door will move normally, closing without stopping.
