Closing Action Control

• A Latch Speed
  Latch control valve allows extra speed to operate in the final stage of door closing to overcome the resistance of the door latch and allows the door to close without slamming.
• B Sweep Speed
  The sweep control valve adjusts the speed of the door during the main arc of the closing action to suit the individual needs.
• C Delayed Action (DA, 180~70 ")
  This option is particularly useful at hospitals and homes for the aged. This function allows convenient passing through the opening, slowing down the closing speed for a preset period when the door opens beyond 70 "
• D Back Check (BC, 90~180" )
  Back check control valve provides you with a temporary stop function between 90" to 180" to help prevent damage to door and/or wall in case the door opens with excessive force. Door stops may still be needed.
• E Spring Power Adjustment Bolt
  This hexagonal bolt adjusts the door opening and closing power from 1 to 5 based on the door weight.
