Delayed Action
An optional hydraulic feature 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°. 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" (3mm) 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. Any time 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 wheelchairs 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 is advantageous are doors between office and factory/warehouse facilities, doors to workshops or laboratories, to kitchen and food processing areas, etc.

ARMS
Non-Hold Open
Self-closes door every time door is opened. Auxiliary stop (by others) required except when using the Holder/Stop, Holder/Stop Spring or UNI Stop™ arms.

Aluminum Alloy Housing: Closer bodies are constructed of a special aluminum alloy, carefully selected
to accommodate interactive steel components and operating conditions.

Rack & Pinion Operation: Provides a smooth constant control of the door through its full opening and
closing cycle. 180° door swing can be achieved when door, frame, hardware and arm function do not interfere.

Non-handed: With few exceptions all 4400 series door closers are non-handed and can be installed on either right or left-hand
swing doors. Pinion shaft extends vertically through the closer body in both directions. 

Sweep Speed Control Valve: Allows adjustment of door speed from the door's full open position down to
approximately 10° from the closed position.

Latch Speed Control Valve: Allows adjustment of door speed from approximately 10° down to the door’s
fully closed position.

Closer Fluid: All door closers are supplied with a temperature stable, multi-viscosity fluid. This fluid will permit the door closer to
perform within a wide temperature range: from very high to as low as -40°F.

Tri-Packed: 4400 series come with screws, brackets and soffit plates to allow for regular, top jamb, and parallel arm installations.

Adjustable Backcheck Cushion Valve: Provides control of the door in the opening cycle, beginning at approximately 75° of door opening. It slows/cushions the door opening when the door is forcibly opened beyond its pre-adjusted limits.

Adjustable Backcheck Position Valve: Allows the door opening position, where backcheck
cushioning begins to be adjusted to a greater door angle up to a maximum of 20º farther (approximately 95º).

Standard Molded Covers: Molded of high-impact U.L. listed material. This cover is non-handed for
all applications. 

Warranty: Limited 25-year warranty for defects and life of the building on the aluminum housing.
