Abloy DC270 Door Closer
This closer is designed especially for ships and extremely heavy doors with sliding arm. It is double closer model where DC247 and DC250 are installed to the same mounting plate under same metal cover.
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.
Adjustable Closing Force
ABLOY DC335, DC240, DC247, DC250, DC330, DC270 door closers are equipped with adjustable spring power which ensures the presetting of spring. Due to adjustable spring power, the same door closer can be used in various applications.
