The 227250-2 application field and its working principle is a further derivative of the already existing 2272 series. Also known as Type 2272, it is a specialty door closer that is designed for medium to large opening doors. It is described as being adjustable in a manner that allows the user to control the speed at which they close the door. The 227250-2 is sometimes referred to as an automatic two-stage closer due to its faster closing capacity when the door is opened beyond a certain predefined angle. The two-stage closing helps to make sure that the door is closed safely and completely, and to prevent forceful slamming.

The working principle of a 227250-2 is based on the same principle as the rest of the 2272 series. When a door is opened, the closer arm senses the action and begins to work. It slows the rate of motion by absorbing the pressure exerted on the arm by gravity as it is opened, thus reducing the door’s rate of closure. The force absorbed by the arm is made up of the “headroom” - the amount of clearance between the door and the frame. Once the maximum headroom is reached, the arm begins to push the door closed in the same manner as the regular 2272 series.

However, the 227250-2 differs in that it can also close doors forcefully if they are opened beyond a certain predefined angle. The “two-stage” principle comes into play; if the door is opened beyond the maximum headroom of 90 degrees, the arm will act as a normal closer until the 80-degree mark is reached, and then it will rapidly close the door. This two-stage mechanism helps to prevent forceful slamming and ensure that the door closes completely and safely.

The 227250-2’s application field is very wide, as it is designed for use in a variety of different applications. It is suitable for overhead and side-hinged doors, as well as fire doors. It is also suitable for use in medical facilities, schools, and business premises. As it is adjustable, it is suitable for smaller or larger door applications. In addition, it can be easily adjusted to the individual user’s preference, allowing them to decide on the rate of closure according to their needs.

In summary, the 227250-2 is a specialized door closer that has been designed to be adjustable according to individual needs. It works on the same principle as the rest of the 2272 series of door closers, but with the added two-stage system that helps to prevent forceful slamming. It is suitable for a wide range of applications, making it a convenient and popular choice for homeowners and business owners.
