Gate closer DIREKT

Technical Data

Function

The gate closer DIREKT operates directly on the gate/door without the help of any lever. It is fixed with one end to the gate post or the door frame and with the other to the door or gate itself.

It operates similarly to a gas spring. When the gate is open, the piston rod of the gate closer is compressed and the pressure of the gas inside the gate closer acts on the piston.The piston rod extends and closes the door/gate. The cylinder of the gate closer contains hydraulic oil, which results in a controlled closing speed that is slowed down. By using nitrogen instead of a helical spring, much higher closing forces can be achieved. Thus the gate closer DIREKT always closes the door/gate reliably despite its small diameter.

Models

Gate closer DIREKT 150 & DIREKT 200 without ascending hinges

Stroke length:

• 150 mm stroke: the standard model for most situations*
• 200 mm stroke: especially designed for wide gates or for those with hinges and posts in unusual positions.*

*For the selection of the appropriate stroke length, please refer to the section installation > mounting positions

Closing force:

• For smooth-running gates and doors that can latch into the lock without effort or that do not have a lock latch, a closing force of 400 N is enough
• If greater force is needed, then you should choose a model with 600 N
• With the help of an integrated valve, the closing force can be reduced on site by releasing gas – only if strictly necessary

Finish:

Gate closer DIREKT for ascending hinges

• Furnished with a ball and socket joint on each side and therefore slightly longer
• The mounting brackets have M8 threads for holding the threaded ends. In general, the same hinge distance as with the normal DIREKT 150 and DIREKT 200 must be observed
• It normally requires less force than the normal models, since the closing of the door is supported by its own weight due to the ascending hinges. The higher the gate ascends when opening and the heavier it is, the less closing force is required. Otherwise too much force would be needed to open. As a basic rule, if the door closes by itself without a gate closer, then the DIREKT with 100 N is the right solution.

Adjustment lock

The adjustment lock prevents users from changing the closing speed. There are two versions available:

Adjustment lock for DIREKT with eyelets: The adjustment lock is slipped over the eyelet and secured with two headless screws. The pressure on the thumb wheel prevents its unauthorized turning.

Adjustment lock for DIREKT with ball and socket joints (for ascending hinges): Here it is not possible to simply slip the adjustment lock on top of the wheel. Therefore this adjustment lock consists of two parts, which can be clipped on from both sides, screwed together and secured with an extra screw.
