Abloy DC240 Door Closer

ABLOY DC240 door closer is suitable for external doors, large doorsand interior doors exposed to conditions of pressure and heavy use.

Operation
Operation is based on a hydraulically controlled rack and pinion or CAM-action mechanism (DC330, DC250). Within the closer there is oil to control the closing and latching speeds and delayed closing and back check features. The adjustable valves enable the adjustment of the speeds and features. Opening a door, the spring inside the closer is becoming tense. When door is released the potential of the spring push the piston back and door closes. Pressure relief valves are standard feature (excluding DC120) to protect the door from abuse and ensure reliable operation in demanding conditions.

Adjustment Valves (C and L)
Closing speed (Valve C): The closing speed can be adjusted 180°- 10° (DC330 and DC250 160°- 10°).
Latching speed (Valve L): The latching speed can be adjusted 10°- 0°.

Backcheck (BC)
A brake affects door movement from 70o - 80o to fully open (180o ) and protects the door by preventing it from being pulled open by the wind. Starting angle can be adjusted by selecting the desired arm position. Adjustment by using valve B.
Recommended for use with external doors.

Delayed Closing (DA)
Delayed closing slows down the movement of the door from fully open (180o ) to approximately 70o , after passing this point the door closes at normal speed. The ending angle can be adjusted by selecting desired arm position. Closing speed can be adjusted by adjustable valve D. Adjustable valve enables the adjustment of closing speed.
Recommended for internal doors.
