SERIES 7500

SPECIAL FEATURE CLOSER

Special Feature Closers

Adjustable Delayed Action Closing: An optional hydraulic feature available that adds a third speed range to the closing cycle. This feature becomes effective when the door is opened and released at any point beyond 70°. Backcheck cushioning and backcheck positioning are standard features with all Series 7500DA/7500BF-DA closer.

The amount of time delay depends upon the combination of the angle of door release and valve adjustment. The valve can be adjusted with a 1 /8" hex key from no delay time up to maximum delay times of:

Pressure Relief Safety Valve: The delayed action hydraulic system contains a pressure relief valve. Anytime the door is forced toward the closed direction, while it is in the closing cycle, the valve will open and permit the door to close. This prevents damage to door, frame and closer.

Suggested Applications: Delayed Action closing allows slow moving traffic to clear the opening before the door closer's normal closing cycle begins. This feature can be helpful in health care facilities such as hospitals and nursing homes. It provides sufficient time for persons on crutches or in wheel chairs to pass through a door without concern of it closing. At the same time it can accommodate the facility's staff with movement of food service carts, beds and other wheeled traffic.

Use of delayed action closers on many doors throughout industrial and commercial buildings can also assist the flow of traffic. Locations where additional time to clear the opening are advantageous are doors to computer rooms, doors between office and factory/warehouse facilities, doors to workshops and to laboratories, to kitchen and food processing areas ... to list just a few.
